Doug Tallamy knows how important a diverse native plant community is for other living creatures, especially insects. He has devoted much of his career to understanding the many ways insects interact with plants, creating essential food webs without which our ecosystems would fail.

His award-winning book and website, Bringing Nature Home, is a call to action for gardeners across the country to use native plants to sustain wildlife, promote biodiversity, and protect our ecosystems.

In his book, Tallamy recounts his own “epiphany” when his family moved to 10 acres in southeastern Pennsylvania, an area “farmed for centuries before being subdivided and sold.” He discovered that “at least 35% of the vegetation on our property consisted of aggressive plant species from other continents that were rapidly replacing what native plants we did have.” And he noticed something else: the alien plants on the property, such as the Norway maples and the mile-a-minute weeds, had “very little or no leaf damage from insects.”

The Native Plant Garden is designed to showcase the beauty of native plants throughout the year. If this were spring, I might be talking about the planting of the woodland, where trillium, lady slippers and ferns were planted in April and May. But this is another time and another season.

Now the meadow is in focus. We haven’t had a meadow in the Native Plant Garden for a very long time–not since the old one succumbed to dodder. But once in bloom, the meadow will be an open, full sun grass garden punctuated with flowers. It has three distinct conditions available for plants, each offering a different environment to support a variety of species.

The new Native Plant Garden got a few new plants recently, to help keep this little oak tree company.

Every time I’ve spoken to a landscape architect or nursery grower about taking an ecological approach to landscape design–something I’ve been doing a lot throughout the planning and development of the Garden‘s new Native Plant Garden–I keep hearing the same phrase repeated over and over:  “You should talk to Colston Burrell.”

Up until this point I’ve known Burrell mostly through his writing. Of recent note is his American Horticultural Society (AHS) award-winning Hellebores: A Comprehensive Guide. This is the time of year when I really start looking forward to the blooming of the Lenten Rose and other garden hellebores, but Burrell’s knowledge goes far beyond the mere beauty of these harbingers of spring. Another book of his that won an AHS book award is A Gardener’s Encyclopedia of Wildflowers. Wildflowers . . .  Now isn’t that just a friendly term for native plants? Burrell is deeply involved with using and promoting native plants, whether he’s lecturing on plants and ecology at the University of Virginia, getting his hands dirty in his own garden, or working on designs through his firm Native Landscape Design and Restoration.

There are a lot of reasons to use native plants. They’re also commonly misunderstood, both  by those who overestimate their powers, and those who underestimate their potential. I’m looking forward to getting a real plantsman’s perspective on how to use native plants in the landscape, the perspective of someone who loves wildflowers and hellebores with equal passion. That’s why I’ll be in the front row on February 17, when Colston Burrell speaks as part of NYBG’s 2011 Winter Lecture Series. I hope to see you there!

Burrell’s lecture is at the Garden in the Ross Lecture Hall on Thursday, February 17, from 10 a.m. – 12 p.m. The cost is $39 for non-members, and $35 for Members. The third and final installment of the series will feature director of The New York Botanical Garden’s Children’s Gardening Program, rooftop farmer, and food advocate Annie Novak on Thursday, March 17.

One of the new stars in the world of native plants these days is Uvularia perfoliata ‘Jingle Bells’. This woodland spring wildflower is indigenous to the East Coast west to the Mississippi. It generally has soft green leaves, yellow bell flowers and an arching demeanor. This new introduction has light green leaves with large white streaks around its border and into its interior. You can find this at Plant Delight Nurseries.

Another native that will attract the attention of homeowners is Amsonia ciliata ‘Spring Sky’. This sturdy native can be found from North Carolina down to Florida and west to Missouri. Blue star (its common name) has won the hearts of many by being a low-maintenance perennial that can grow in sun or part-shade and has the added benefit of being deer and rabbit resistant.

This new cultivar is a compact version of the native – reaching only 2 feet tall by 2 feet wide. It has pale blue flowers in the spring that are slightly larger than the native and fine, feathery foliage that turns a beautiful yellow hue in the fall. This new introduction comes from North Creek Nurseries.

For those of you looking for a splash of color later in the season, there is a new goldenrod on the market named Solidago ‘Solar Cascade’. ‘Solar Cascade’ size falls somewhere in between the compact ‘Golden Fleece’ and the majestic ‘Fireworks’. ‘Solar Cascade’ is a clump forming perennial that is drought tolerant once established.

‘Solar Cascade’ has glossy green foliage and arching sprays of golden flowers late in the summer. It will pair beautifully with many of your late season staples – ornamental grasses, New York ironweed (Vernonia noveboracensis), medium sized dahlias and annual late season salvias.
A new cultivar of an ornamental grass that is indigenous to the dry plains of central North America is hitting the market by storm this year. Sometimes referred to as mosquito or blue grama grass, the new cultivar is named Bouteloua gracilis ‘Blonde Ambition’. read more »

Native plants have always been at the heart of The New York Botanical Garden. The site where the Garden now sits was, in large part, chosen by founding director Nathaniel L. Britton in 1895 because of the site’s 50-acre old growth Forest and its vibrant population of native plants. Britton‘s wife Elizabeth was a passionate advocate for native plants and a founding member of the Wildflower Society, one of the earliest groups dedicated to the conservation of the native plants of North America.

The new Native Plant Garden reached a milestone today. Learn more below.

The Botanical Garden’s living collections is among the greatest in the world and contains more than 1 million plants. Jon Peter, Plant Records Manager, periodically shines the spotlight on a particular species that can be found within our 250 acres.

Botanical Name: Sassafras albidum

Common Name: Sassafras

Family Name: Lauraceae (Laurel family)

Native Range: USA—Maine to Florida, west to Michigan and Texas
Canada—southern Ontario

USDA Hardiness Zones: 5 through 9A

Locations within NYBG: Forest, Everett Children’s Adventure Garden, Native Plant Garden

Site Requirements: Sun to partial shade; well-drained, moist soil

Interesting Note: This species has been used for centuries in a variety of ways. The root bark was used to flavor root beer, the leaves and bark used to make tea, and the oils used in soaps. It was known in folk medicine as a tonic and a purifier of the blood and still has a reputation as a stimulant, and as a treatment for syphilis, rheumatism, and skin disease. Most of these uses ended in the early 1960s when it was found that the active ingredient safrole is carcinogenic.

In the native habitats of North America it has exceptional valuable as a food source for insects, birds, and mammals. The sassafras has many great ornamental qualities as well: from its gorgeous furrowed bark and three forms of leaves to its fragrant twigs and beautiful autumn color. Sassafras is under utilized in the North American landscape.

Last week I blogged about Doug Tallamy’s book Bringing Nature Home and the natural life cycles and interdependence among species in an ecological community. What happens when the balance of nature is disrupted?

The problem usually arises when an invasive species comes in and completely overturns the equilibrium—a process in which humans are intimately involved.

Not only are we generally responsible for introducing exotic, invasive species, we also mangle the environment with construction equipment, paved roadways, big lawns (a great American monoculture), and other means that disrupt natural communities. These disturbances provide invasive species with an ideal opportunity to colonize. read more »

The lovely title of Douglas Tallamy’s acclaimed book Bringing Nature Home implies that as gardeners and environmentally minded citizens, one of our directives is to invite nature—birds, bees, butterflies, and other critters—into our landscapes.

As I wrote about in the past few weeks, invasive plants change face of our natural landscape, and so do pollution and urban sprawl. In his book, an outstanding homage to biodiversity, Tallamy looks at two other destructive forces: habitat destruction and the loss of species.

Biodiversity is synonymous with a balanced ecological community. Plants, insects, and other animals have all co-evolved in communities with complex, interconnected lives that are dependent on one another.

Many insects are specialists, meaning that they feed on specific plants. This is nature’s way of ensuring that species are not decimated by predators. How do plants do this? read more »
