Blues…. not the sad kind but the wonderful colorful shades ranging from steel blue to lavender. Of all the colors found in garden flowers, blues are probably the lease common. Since our climate appears to be changing for the warmer the following plants mentioned will be more on the drought tolerant side.

As in flower arranging so in the garden, the blues & purples seem to disappear when seem from any distance. This shouldn’t discourager you from planting them. Keep in mind that light colored blooms of white or yellow planted around the blues will help their visibility greatly.

One of my favorite flowering shrubs is Buddleia, the butterfly bush. The first time I saw one of them was on a garden tour years ago. It was about 6 feet tall and absolutely alive with scores of butterflies and even a few humming birds, all after the nectar. The many varieties have a color range from almost black to light lavender to maroon reds and white. There are even dwarf varieties. The flowers come from each year’s new growth so hard pruning can be done either in the fall or spring if you want a shorter shrub

If you lean towards the purples try the beautyberry shrub Callicarpa. A new one just on the market scene is a variety called ‘Purple Pearls’. This 4-5 ft bush has fuzzy pink flowers followed in the autumn by intensely bright purple berries which surround the stem. The purple foliage gracefully drape to the ground. Cut stems give a real splash of color in an autumn arrangement as well as being striking in the garden. The violet-lilac berries attract birds and are claimed to repel mosquitoes. This is another shrub that blooms on new wood. . For those who like variegated leaves there is a white beautyberry variety.

For a really true blue flowering shrub consider Caryopteris with the common names of Blue spirea. Blue-mist, Bluebeard. It blooms late in the summer, is drought tolerant, pest resistant and virtually maintenance free. Its blue flowers are very popular with butterflies and hummingbirds. These shrubs native to the Himalayas, bloom on new wood each year so when to prune is not a problem. Their maximum height is only 4 feet.

For a very wide choice of blue varieties, consider the salvias both annual and perennial. They are some of the most versatile plants around being drought tolerant, they have both attractive blooms and foliage, pleasant aroma and most critters usually ignore them. Mystic Spires, Blue Angel, Evolution, Victoria are just some of the annual varieties. If you want a patriotic garden then plant one of these blues with white and red annual varieties. As I have been watching old re-runs of MASh recently, the salvia variety called Hot Lips kind of jumped out at me. It is a perennial with white flowers with bright red kiss shaped markings. Among the culinary varieties are the regular sage {Salvia officinalis}, used for poultry stuffing as well as purple, variegated and tricolor. Perennial varieties include May Night, East Friesland, Sensation and Plumosa. There is one biennial I am familiar with called Salvia Artgentea or Silver Sage. It has very large fuzzy leaves softer than “Lambs Ears” which everyone just has to touch.

Next time you are browsing through seed or plant catalogs or anticipating your next purchase at a nursery, consider adding some of the blues to your garden.

Plants to Consider

by Jeanette Mac Kenzie

If you haven’t been growing the following plants, you may want to consider them when placing your seed orders this month.

The first one is Platycodon, better know to most gardeners as “the balloon flower.” Before it opens it has the shape of a hot air balloon. Vita Sackville-West (a famed author, poet and garden designer of Sissinghurst Castle gardens) described the balloon flower’s puffed-up bud as “a tiny lantern, so tightly closed as though its little seams had been stitched together, with the further charm that you can pop it . . . if you are so childishly minded.”

Its botanical name comes from Greek meaning (broad bell). In 1877 Charles Maries discovered the blue balloon flower in Japan. He also discovered close to 500 other flowering plants in both China and Japan. Plant collection and discovery was no easy job in those days. He survived earthquakes, fire and a shipwreck, but his plants often did not! He once had to retrace his entire journey to replace a whole collection, when a box of his seeds was in a boat that capsized and sank.

The balloon flower is an under-used perennial in our gardens. It is fairly easy to start from seed but doesn’t bloom until the second year of growth. If you are impatient, just buy a plant. Since blue flowers are somewhat uncommon, the balloon flower is a good one to grow in your garden. It also comes in white and pink with some varieties having double petals. My favorite blue is one called Komachi, which doesn’t open at all—it just stays in its balloon shape. The plants will take full sun to half a day in average garden soil. As a cut flower you immediately need to sear the cut end with a flame for it to hold up in an arrangement.

The second plant’s botanical name is Lathyrus  odoratus, which translates to “fragrant peas.” Surprisingly enough, they are not members of the pea family, Pisum savitum, even though they look alike. Peas such as the snow pea, English shelling pea and sugar snap peas are all edible. Despite the name sweet pea it is poisonous with serious consequences including convulsions, paralysis in the legs and unconsciousness. The word sweet describes the scent of the blooms—not the flavor!

A Franciscan monk in Sicily discovered sweet peas in 1697. He sent the seeds to a botanist in England (Dr. Robert Uvedale) who was interested in rare exotics. Uvedale first raised the sweet peas in his hothouses, but eventually discovered that they were hearty outside.

The original sweet peas were purple and quite small but very fragrant. Over the years there has been much hybridizing resulting in different colors, combination of colors, sizes and fragrances. In 1900 there were about 300 varieties; it is unknown how many there are today.

The climbing vines average about six feet in height, while dwarf/bush varieties are just a foot or two. The longer vines need some source of support such as string, netting, arches or just a bush to climb on.

Sweet pea seeds should be soaked for 24 hours then nicked OR rubbed with sandpaper to break the hard seed coat. They should be planted early in spring when the soil is only 55-60 degrees. Be patient as germination can take from two to four weeks. The plants like full sun with shaded root area, so either add mulch or plant annuals near the base of the sweet pea plants.

By the way there are both annual and perennial varieties of sweet peas. Plant them where their fragrance can be enjoyed near an outdoor sitting area or near where you open windows in the summer.

Although a bit on the short side, cut bouquets of sweet peas can add wonderful fragrance to your home and are very striking with their bright as well as pastel colors. The only problem I have found with sweet peas is trying to narrow down my choices whether online, in seed catalogs or at a local nursery, with names like Old Spice, Antique Fantasy, Rose-Pink Mammoth, Incense Peach Shades, Turquoise Lagoon and High Scent.

As you peruse your seed catalogs this month, consider adding Sweet Peas, Balloon Flowers or both of these plants to your gardens this summer.

Next Season's Vegetable Garden

by    Jeanette Mac Kenzie

Next Seasons Vegetable Garden by Jeanette Mac Kenzie Since winter is still with us for a few more months, outdoor gardening activities a re severely limited. However, you can do some daydreaming and planning by looking through seed and plant catalogs. To help you do this I have made a chart stating approximate times to plant vegetables. To help plan for successive plantings, information on harvest times is also included. Days to harvest depends on the variety of vegetable, whether direct seeded or transplanted and the weather.

How Plants Handle Cold Weather

by Jeanette Mac Kenzie Dec. 2016


When I was in college, many years ago, I had a part time job working in Horticulture. I was doing some nitty-gritty stuff for Dr. Lee, who was researching how plants survive the cold Minnesota winters. Some of his research led to the information I am presenting today.


Tropical and warm climate plants are kept inside as they have no protection from the cold— we call them HOUSEPLANTS!


When ice forms inside a plant cell it is lethal—this is how plants die in the fall and winter. Yet in cold climates, plants have adapted ways to come through the sub-freezing temperatures of a northern winter with minimal damage.

iced oranges 

Method 1: One way that plants tolerate freezing temperatures is by forming ice outside the plant or outside the plant cell walls in a process called “Extra-Cellular freezing).” You have read or heard on the news when there is a frost expected in the Florida citrus orchards, the trees and fruit are sprayed with water which freezes and protects the fruit following the principal of extra cellular freezing.


Method 2: Some plants have Freeze-Tolerant Cells. When water freezes outside the cell, the water inside the cell moves outside to form more ice. This reduces the amount of water within the cell. It also concentrates the sugars and other things in the cell, forming a natural antifreeze.


Method 3: Some plants do something called “Deep-Super-Cooling." By adding other substances to the inner cell it, changes the freezing point of water in the plant cells. An example of this is when salt is added to water, it doesn’t freeze at 32 degrees. Some plant species can fluctuate in their tolerance to cold in response to the changing day-length and temperature. In the fall the development of hardiness is a slow, gradual process. In the spring the loss of hardiness is dependent upon temperature. This is why after a nice warm spell in the spring, plants start growing. If however this is followed by a frost, the plants may die or as in the case of fruit trees lose their ability to produce fruit that year.


This is probably why most of your hydrangea plants didn’t bloom at all, or only very sparsely this year.


Roots in general are less hardy than stems or any above-ground plant tissues because roots are exposed to less cold under the ground. A plant or shrub planted in the ground will survive while the same type plant growing above ground in a container or window box is much more apt to die. In general, tissues that are actively growing are the least hardy. In the spring avoid fertilizing your plants until the risk of a freeze is definitely over. This is usually mid-May.


After an early spring warm spell you may want to try a product called Freeze Pruf to give your smaller plants a helping hand. It is a liquid-based spray that enhances the plant's natural mechanisms to resist freeze damage by reducing the freezing point of the water inside the plants tissues. It lasts from 4-6 weeks. As Freeze Pruf can be expensive, you may want to do some price shopping at Amazon or Walmart.


So now you know a bit more on how plants survive cold winter temperatures.

There’s Danger in the Woods & Wet Lands

                                                                                                                                                        by Jeanette Mac Kenzie

No, not from spooks and goblins, but from some very colorful autumn leaves that you may be tempted to gather for fall decorating. As a young child, I recall seeing several women exiting Nerstrand Woods in southern Minnesota, delighted with their armfuls of vines with vibrant red leaves. I was too shy to tell them what they had picked, but ran to tell my mother what I had seen.  You may have guessed that these unfortunate women were carting home poison ivy to decorate their homes.

The old sayings, “Leaves of three, let them be.; Hairy vine–no friend of mine.; Berries white, run in fright.” are good ones to follow especially if you are not familiar with identifying poison ivy (Toxicodendron  radicans). The three leaves are all on one stem but not attached to each other. In the old cowboy movies the good guys usually wore white hats. This doesn’t hold true for the bad guys—poison ivy and poison sumac—as they both have berries of white. Birds and animals eat the white berries and disperse them around the countryside. This explains why you can unexpectedly find poison ivy on your property where it never used to exist.  

Poison ivy can be found growing along the ground and as an aggressive vine climbing anything it can find.  It is one of the first plants to turn fall colors, and the leaves can be among the most beautiful. The leaves vary greatly in size, shape and range of colors and patterns.

             2.poisonivy fall colors    3.poison ivy berries

Another nasty relative is poison sumac (Toxicodendron vernix) that grows as a small tree. This is almost always found in damp wet areas. It has smooth-edged leaflets and white berries. The more common look- alike plant is the staghorn sumac, (Rhus typhina), which has large red fruits and a velvety texture to its stems and saw-toothed leaf edges. Both plants have double rows of leaflets on a long stem, colorful leaves in the autumn and are occasionally found growing right next to each other, to further confuse you.

               4.poison sumac fall color    5.Poison sumac with berries red stems

There is still another plant to look out for in the woods, called poison oak (Toxicodendron pubescens). 

poison oak

This plant also has leaves of thre but they can be serrated, round or oak like, depending on what other plants are growing nearby. I’ve never seen an explanation as to how the plants decide to mimic their neighbor’s leaves. The poison oak can grow along the ground or be a vine. Luckily we don’t have to worry much about poison oak as it is rarely found growing in New England.

The same toxic substance URIUSHIOL is found in all three of these poisonous plants. Up to 85 percent of Americans are allergic to uriushiol. It quickly penetrates the skin after exposure, either from touching the plant or touching pets–garden tools–etc. that have touched the plant. If you burn wood beware of any logs that have imbedded vines on them. I say this from personal experience!  Uriushiol oil can be active on any surface including dead plants for one to five years. Worst-case scenario is airborne contact from the smoke of burning these plants. Burning releases particles of urushiol into the air that can penetrate the skin, eyes, nose, throat and respiratory system.

Years ago a large percentage of the Norwell volunteer fire dept was laid up after fighting a fire that got into nearby woods which was loaded with poison ivy.

Symptoms of exposure include: red streaks, rash, extreme itching, blisters that weep, swelling, inflammation and a burning sensation.

Learn to recognize the leaves and fruits of these plants and teach your kids and grandkids about them.  There are lots of good photos on the Internet to study. Enjoy your walks in the woods and elsewhere outside, but be careful what you touch or brush with your clothing and footwear.

October 2016

October has arrived and with it the long awaited rain. Things are greening up fast – including weeds. “When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant!

*Early in October is the best time to plant your garlic and shallots to be harvested next summer.

*Continue to mow the lawn as long as it is still growing.

*Fall is the best time to dig and divide peonies. Remember not to cover the growing buds/eyes with soil more than 2 inches deep, or the plant will not bloom.

*Dig and store dahlias, cannas, tuberous begonias and gladiolas when the plants begin dying down.

*Cut down stems and foliage of herbaceous perennials when the leaves begin to brown, leaving 2-3 inches. If the plants have lots of seeds (like coneflower and sunflowers) you may want to leave them for the birds.

*Take time on a sunny day to collect pinecones, acorns, gourds, milkweed pods, iris pods, teasel and other goodies for autumn and winter decorating. Keep in mind the club’s Greens Sale in December.  

           corn gourds          gourds


*Leave parsnips and Jerusalem artichokes in the ground until after a frost, which will sweeten them. Broccoli, cauliflower, Brussels sprouts can handle a frost, so leave them in as long as they are still producing.

*Plant spring flowering bulbs—such as tulips, daffodils, hyacinths, crocuses—for a splash of color next spring.

*Have a family outing at a pick-your-own apple orchard, unless of course you have your own fruit trees.

*Don’t be hasty in applying winter mulch to your perennials. If applied too early, mulches can do more harm than good. The mulch is used to keep soil temperatures constant and prevent frost heaving, not to keep it warm. Apply mulch when the temperature is at freezing (32 degrees F). This is usually around Thanksgiving or when the first icy crust has formed. 

*Don’t be concerned to see the browning of evergreen needles closest to the trunk of the tree. This is natural and happens yearly.

*Take a little time to walk through your garden to evaluate what did or did not work and note what changes you want to make next season. Be sure you write these thoughts down, and remember where you put the list!

In just a few short months the new seed and plant catalogs will be arriving in our mailboxes, and we can begin dreaming about how spectacular and productive our 2017 gardens will be!

The Color Green

                                                                                                              by Jeanette Mac Kenzie

Green — the color of most growing plants — has been a bit more on the beige side this summer due to the drought, especially on our lawns. Never the less, with fall rain, winter’s snow and spring rain, the green will return again.

We don’t necessarily like the color green/blue in our eggs unless it is in the egg shells laid by Araucana, Ameraucana or Easter Egger varieties of chickens.

Green broccoli, spinach, peas, beans, and chard are all healthy green vegetables that we grow and eat with safety.

Potatoes on the other hand are a different story. Potatoes might be one of the most versatile, inexpensive, filling, and nutritious foods on earth. But while you might not think twice about just cutting up a potato and cooking it, there’s actually one important thing you should be paying attention to first: the color. Specifically, the color green indicates a toxic poison is present.

The presence of chlorophyll in a potato means that a glycoalkaloid poison named solanine is also present. A defense against insects, this nerve toxin (which is in the nightshade family) can result in headaches, vomiting, diarrhea, and even paralysis if ingested in very high amounts. So NEVER eat any potato leaves, stems, or sprouts, and it’s probably wise to avoid eating any potatoes that have a greenish tint.

I’m not trying to fear monger here. If you eat that odd green potato chip or end up mashing up a slightly greenish potato into your Thanksgiving side dish, nobody’s going to get sick. According to Snopes, a healthy adult would need to eat more than four pounds of green potatoes in one sitting in order to have any neurological side effects. Children, however, due to their smaller size, are more susceptible.

So, be on the lookout for any green in your potatoes, which can come from excessive light, cold, or heat. You’re not going to die if you eat it, but you will be ingesting trace amounts of a nerve toxin.

When digging your potatoes, get them out of the sun immediately and don’t store them where they are exposed to light.


Top your tomatoes. Most varieties of tomatoes are ‘indeterminate’, meaning the vines will keep growing until killed by frost. By cutting off the top of your tomato plants down to where fruit has already set, you encourage the plant to put its energy into ripening the fruit already on the vine rather than generating new leaves and flowers.

Enjoy vegetables this fall. It’s not too late to plant some vegetables for fall harvest. Start by inventorying your leftover seeds. Do you have peas, spinach or lettuce? Plant them now; they have plenty of time to produce a crop. How about Tokyo turnips? They are ready to harvest in a month. Read your seed packages with an eye to ‘days to maturity’, then count back from the first frost date, mid-October for most of us.

Row covers are back in fashion. The row covers you used in May and June to keep out bean beetles and other bad bugs can be pulled out again, this time to provide a few degrees of nighttime protection against cold. Check your town’s swap area for hard plastic or glass covers (old doors or windows work well) to give you a simple cold frame that can keep your garden growing until covered with snow. You can add 60 days or more to your growing season.

What to compost; what to bag and discard. As you remove spent plants from your vegetable garden, look at each one with a critical eye. Send any plant that is either diseased or infested with bugs to the dump. Compost the clean plant material to create ‘Black Gold’ for next year’s garden.

Clean up your yard. Take advantage of cooler mornings and evenings to do the weeding we avoided in August. If it seems like weeds were the only things that managed to grow during the drought, it isn’t an illusion. Weeds such as crabgrass thrive in dry soils. Reward that hardiness with a good tug and a trip to the dump. Every weed that goes to seed means many more to deal with next year.

Think twice before you rake. While cleaning your yard, remember the leaves that fall are food for the plants. Use a mulching mower to chop up the ones on the lawn. They will finish disintegrating over the winter. Under bushes and around perennial beds, fallen leaves serve as a winter mulch and a home for many beneficial insects like butterfly caterpillar, so please don’t chop them and leave them be.

Freshen your containers. It has been a tough summer for plants in containers. The unrelenting heat and the regular dousing with chlorinated tap water (in place of the non-existent rain) is not conducive to a long happy life for your annuals. It’s too early to use cut evergreens, so consider putting in some transitional plantings such as the multi-colored kale, perennial grasses and heuchera. Avoid using mums. They aren’t a good choice if you like to keep the season going until Thanksgiving because the flowers will die long before that. 

Divide and multiply. September and October are great months to dig and divide overgrown perennials that bloom early. Creeping phlox, oriental poppies, foxglove, delphinium and iris are all candidates. You can also dig and divide later blooming plants such as hostas and many ground covers. Spread them around your property, share them with friends or pot them up for your garden club’s spring plant sale. They will be healthier and look better if you don’t wait until spring.

Benign neglect for your lawn. The summer heat and water bans have been tough on everyone’s lawns, but don’t try to rehab them this autumn unless Mother Nature suddenly provides us with lots of rain and the watering bans are ended. Apart from pulling crabgrass and other obvious weeds before they set seed, leave your lawn be. Grass is a hardy, cool-weather perennial, and there are steps you can take later this autumn and next spring to enhance your lawn. 

Spring bulbs?  Not yet, but soon. Wait until the soil temperature has dropped to 55 to 60 degrees several inches below the surface to plant spring bulbs. This usually occurs after several weeks of nighttime temperatures in the low 50s. Putting bulbs into warmer soil may cause them to begin growing tops (which is bad) when they should be growing only roots to support the flowers next spring. Now is also a good time to dig up any bulbs that have been in for a few years. You’ll likely find they’ve multiplied and are now crowded (yeah! free bulbs) and need to be thinned; or have been attacked by moles, voles and other varmints and need to be replaced.  Add lime over old and new bulbs now, but fertilize only after they are in bloom in the spring.

Critters & Varmints

                                                                                                                                                        by Jeanette Mac Kenzie
August 2016

With an official heat wave and drought currently underway most of our gardens and lawns aren’t looking too happy.  Water restrictions limit the particular days and time of day we can get moisture to our plants.

If that isn’t bad enough the plants that are surviving are a tempting meal for assorted critters and varmints.  As a kid the word varmint was used for the “bad guys” in the cowboy movies of Roy Rogers, Gene Autry, Hopalong-Cassidy Red Rider & Little Beaver and the Lone Ranger  & Tonto.  I realize I am dating myself with this list!   Today I am referring to 4-legged varmints who eat your gardens.

You most likely have tried some of the many suggestions to dissuade these animals with varying degrees of success.  I have a new suggestion that only a few of you have used.  The names of the companies that supply the magic ingredient will give you a good idea what I am suggesting: Leg-Up Enterprises, Pee Mart and Predator Pee.

“Predator urine concept is based upon the principal of duplicating the use of urine by animals in the wild. Predators mark the perimeter of their territory with urine.”   By simulating the powerful genetic fear reaction garden pests like deer, skunks, chipmunks, rabbits, etc. avoid areas where their predator’s urine has been sprayed or applied - namely around your garden. 


Sources for this commodity come from game farms, zoos and preserves.    The question everyone has but doesn’t want to ask is: How is the pee collected?    For a humorous description check out www.predatorpeestore  under the heading How Do We Collect Pee.  It is long but well worth reading.  This source also supplies numerous types of animal urine. 

You must determine which critters are munching your garden before you can decide which type of predator urine to order.  Coyote urine works for deer, woodchucks, raccoons, possums, and rats.   However for moles & voles choose bobcat urine, and for the little fellers such as rabbit, squirrels, chipmunks choose fox urine.  The site mentioned above has lists of what to order for the varying garden pests.

Hope this suggestion helps to preserve your gardens.


Should I water, or is it going to rain?

No, not the ones that give you that soft light at the dinner table.

The candles I am talking about are the prominent terminal buds that emerge from pine shrubs and pine trees in the spring. These slender, light green, new growths resemble candles. By breaking off 1/3 to 2/3 of this growth each spring, your pines will be controlled in height as well as being much fuller. With or without gloves, the candles can easily be broken off with just thumb and forefinger. Small hand pruners will also work, but don’t use hedge trimmers. This may be a project for kids!

For most evergreens it is recommended to prune when they have finished their period of growth in late summer or fall. Pines are the exception as they should be pruned when in active growth. Whether you have the common white pine, dwarf blue Scotch pine, weeping Japanese red pine or Hillside Creeper (this is a real plant not something from the police report), late May or early June is the time to do your pruning / candling by breaking those candles.
