On The Bookshelf: The Green Garden: A New England Guide

joenesgarden — Wed, 11 Jan 2012 18:24:22 +0000

Are you a New England gardener seeking a good gardening book in which to lose yourself during cold winter months? Look no further than Ellen Sousa's book The Green Garden: A New England Guide to Planning, Planting & Maintaining the Eco-Friendly Habitat Garden.

Sousa is a fellow garden coach and a natural gardening instructor. She holds a certificate in Native Plant Horticulture & Design from the New England Wild Flower Society and has written about habitat gardening for National Wildlife Federation and other magazines. Sousa writes for a few blogs, including Native Plants & Wildlife Gardens, and the Massachusetts farm she shares with her husband is a Certified Wildlife Habitat and Monarch Waystation.

She walks the walk and talks the talk.

Now she has compiled an extensive and comprehensive guide for other New England landowners interested in making their property more user-friendly for non-human naturally-residing creatures and, ultimately, more enjoyable for human residents as well.

Sousa explains the what, why, and wherefore of habitat gardening in rural, suburban and urban areas in addition to forests, fields, fresh and saltwater shorelines, and wetlands.

She explains how to replace lawns – or most of a lawn - with diverse plantings needing less human input.

She describes how to begin transforming a patch or a property to a wildlife habitat - perhaps as simply as insuring a fresh water source for birds or planting nectar sources for butterflies and moths- and how continue the multi-year process.

Sousa separates plants as:

· New England natives - growing in New England prior to European settlement. Think violets, goldenrod, hemlock and oak;

· naturalized non-natives - plants that native creatures have adapted to and count on. Think Queen Anne's lace;

· introduced non-natives - cosmos, peonies and nasturtiums - brought to New England as ornamentals or edibles. These provide some nectar, pollen or seed benefits to native wildlife;

· and to be avoided and controlled invasive non-natives like Asiatic bittersweet vines that overpower and destroy trees and the purple loosestrife overtaking many New England wetlands.

Then, so readers are not left guessing, she offers more than 40 pages of specific tree, shrub and plant recommendations keyed for their habitat value (attractive to birds, butterflies and moths, amphibians or mammals) and growth characteristics (light and water requirements, deer resistance, ease of growth, etc.).

Sousa further provides lists and links to more information, source nurseries, public habitat gardens, and wildlife gardening organizations, just in case readers crave even more guidance and learning.

The Green Garden: A New England Guide to Planning, Planting & Maintaining the Eco-friendly Habitat Garden is a wonderful primer for those just learning about natural habitat gardening, but it's also a valuable educational resource for seasoned gardeners seeking to hone their habitat gardening knowledge.

It is one of the books I'll reach for time and again as I care for my property and continue to urge others to garden thoughtfully.

Make a difference. Plant natives.

joenesgarden — Thu, 28 Jan 2010 02:07:23 +0000

Garden as if life depended on it! Doug Tallamy wrote these words in my copy of his book, Bringing Nature Home. No, I'm not a special friend or acquaintance, he wrote similar, if not identical words inside all the books he signed that day. On the other hand, though, I am special. I'm a gardener with extraordinary power … I can choose to plant whatever I want. You are also extraordinary, as you have exactly the same power as I. And if we, as gardeners, do just a little of what Tallamy suggests – increase the number of native plants growing in each of our gardens– we, individually and together, may be able to make a significant difference in the nature of our future.

Professor Tallamy chairs the Department of Entomology and Wildlife Ecology at the University of Delaware in Newark. There he teaches insect taxonomy and ecology courses and researches how insects and plants interact. You can delve into his research simply by searching his name in Google Scholar. You'll see studies like Squash beetle feeding behavior in the journal Ecology, or Effects of non-native plants on the native insect community of Delaware in Biological Invasions … you get the picture, he's an insect junkie. But he's still able to write compelling, and very readable non-scientific explanations of the side-by-side evolution of local insects and local plants that enables them to support not only each other but the many birds and other creatures farther up the food chain … and how non-native plants are simply not as palatable or user-friendly, so to speak, to local insects … and when faced with fewer or no native food, insects either vastly decline or disappear … and when this happens local birds have fewer insects and caterpillars to feed their little bird babies … and weaker or fewer bird babies means fewer birds to feed other creatures farther up the food chain. Ok, any grammar or English teacher reading this is probably cringing at my run-on sentence, but I think I've made my, or more correctly Tallamy's point. Fewer natives = fewer bugs = fewer birds = less food for all.

Time and again Tallamy has found substantially more insect biomass (bird food) surviving on native shrubs, trees, and plants as opposed to alien greenery growing in the same area. One of his students, Meg Ballard, as her master's thesis, conducted a two-year comparison of insect biomass (bird food) found on six herbaceous natives – eastern black nightshade, black-eyed Susan, devil's beggarticks, ragweed, horseweed, and goldenrod – and six herbaceous aliens – lambsquarters, cocklebur, velvetleaf, jimsonweed, pigweed, and cosmos. Compared with aliens, the natives produced nearly 6-times more generalist insect herbivore biomass – that's science-speak for insects that eat just about any plant (generalists) rather than specialize on specific plants and therefore provide a good amount of bird food. This comparison produced no evidence that generalists prefer alien plants, Tallamy writes, or that alien plants produce as much insect biomass (bird food) as native plants.

Some of you are likely thinking, 'You want me to plant plants that attract more bugs?' The short answer is yes. More native plants = more native bugs = more bird food. An example is black-eyed Susans. They grow with virtually no work, offer color throughout mid to late summer, and provide food for local birds.

Tallamy's arguments for planting natives focuses more on trees. Consider oaks (Quercus), the mightiest when it comes to supporting Lepidoptera species (moths and butterflies). Oaks support 534, followed by willows (Salix) and cherry or plums (Prunus) at 456 each, birch (Betula) at 413, poplars/cottonwoods (Populus) at 368, and crabapples (Malus) at 311. Whereas beech (Fagus) support just 126. (Get the book and read the list on page 147.)

Bringing Nature Home includes color photos of native trees, native perennials, and native insects, as well as lists of natives for all regions of the continental U.S. – sorry Alaska, Hawaii, and other island locales - and this alone makes it a valuable reference. It also argues persuasively that gardeners move away from planting only for aesthetics and toward planting more to achieve a balanced food web. Tallamy even cites the success he and his wife have had in converting their own suburban yard from a lawn near-wasteland to a richly diverse insect-laden, bird-friendly, native-plant haven.

Humans have disrupted natural habitats in so many ways and in so many places, and this is increasingly evident in ever decreasing numbers of amphibians, butterflies, birds, and other creatures. But as gardeners and stewards of our land, we are empowered to reverse some of this disruption, simply by planting natives.

I, for one, plan to rise to Tallamy's challenge by planting more shrubs and perennials native to Connecticut. Check out the links below to learn how you can be so empowered as well.

Attracting Bluebirds

joenesgarden — Fri, 23 Oct 2009 22:40:14 +0000

October 23, 2009. If you need a good reason to plant more natives in your landscape, keep in mind that doing so will help attract bluebirds. Bluebirds are attracted to berry-bearing trees and shrubs, such as dogwood, shadbush, and high bush cranberry, according to a Connecticut Department of Environmental Protection (CT DEP) fact sheet. Check it out to learn other plants and shrubs that attract bluebirds, plus other important bluebird facts, breeding and nesting particulars, and how to build and situate bluebird nesting boxes. And, if you are part of an organized group looking for a cool project, you can reserve the wood for bluebird nesting boxes from CT DEP … but hurry, it's on a first come, first served basis.

Watching bluebirds flit about is a great winter pastime – the electric blue of their feathers really shows up against a snowy white background - and now is a good time to improve the bluebird attractiveness of your surroundings. I often see bluebirds visiting the winter wreaths I place on entry doors, especially when I'm able to find juniper greens loaded with steely-blue berries. The National Wildlife Federation lists the top ten natives for the northeast U.S. as:

Eastern Red Cedar (Juniperus virginiana)
Black Tupelo (Nyssa sylvatica)
Northern Red Oak (Quercus rubra)
Winterberry (Ilex verticillata)
Sweet Pepperbush (Clethra alnifolia)
Red Chokeberry (Photinia pyrifolia)
Blue Vervain (Verbena hastate)
Rough-stemmed Goldenrod (Solidago rugosa)
Cardinal Flower (Lobelia cardinalis)
New York Ironweed (Veronia noveboracensis)

The Connecticut Botanical Society lists many of these plus mountain laurel, bayberry, rosebay, some azaleas, fragrant sumac, high bush blueberry, plus others – follow the link to see photos.

I'm lucky to have cedar, red oak, blueberry, and cardinal flower all growing naturally nearby. Previously I planted winterberry, clethra, bayberry, and solidago.

With any luck the new holly bush (Ilex meserveae 'Blue Maid') planted a couple of weeks ago will add to my yard's bluebird appeal.

Seminar: Going Native in New England

joenesgarden — Sat, 17 Oct 2009 13:16:03 +0000

October 17, 2009. One of my favorite fall bright spots come from the blueberry bushes I have planted in a perennial border and those growing naturally in the woods surrounding my home. Native blueberries are wonderful replacements for the potentially invasive burning bushes (Euonymus alatus) planted along highways throughout Connecticut in so many yards – even in mine which includes one closely watched 'Compactus' variety planted a long time ago. Now, when I seek burning red color I plant blueberries, like the low-bush variety in the photo.

Learning what is and is not native is an increasingly important part of gardening. The Connecticut College Arboretum, located in New London, is sponsoring a day long seminar for homeowners interested in using more New England native plantings around their homes.

Speakers and topics include:

Dr. Doug Tallamy on how diverse collections of native plants provide food for insects and birds,
Stephanie Cohen on underused native perennials,
Laura Eisener on native vines
and Robin Wilkerson on native alternatives to invasive plants.

While not free - $70 for the general public – this fee includes slide presentations and lectures on the topics above, a continental breakfast, lunch, two breaks, and as usual, the chance to speak with presenters and purchase books. If interested in this Saturday, November 7, 2009, 9 am to 3:30 pm seminar, you must register by October 30. See the seminar brochure for registration information.
