Why and How to Buy Native Plants

96% of birds needs insects, not just nectar or seeds, to raise their young.

90% of insects eat only native plants. (Douglas Tallamy, Bringing Nature Home, p. 72)

As Tallamy explains, the untouched wild places in the U.S. cannot by themselves support the native birds, bees, butterflies, and other creatures that are essential to life on earth as we know it. We must use our gardens and landscaped areas.

Every time you plant a native plant, you do your share toward this critical task.

But don’t just buy a packet of Burpee seeds labeled natives–they often contain seeds of plants not native to your area. And do not just pick up any plant labeled “native” at your local nursery or big box store: the label can be used loosely and deceptively.

It is important to distinguish among three types of garden plants:

  • Natives are plants that evolved in a particular geographic area. They support a wide variety of insects, birds, and animals that co-evolved with them in the same geographic area.  The word “native” can be interpreted locally or more broadly. For example, a plant may be native to the Connecticut River Valley, but not native to Hampshire County.  A good practice is to plant natives from as close to home as possible.
  • Cultivars are plants imported from somewhere else and bred for qualities that humans desire. They generally support far fewer varieties of insects, birds, and wildlife than natives.
  • Nativars are native plants that have been bred for qualities humans desire. Usually, they are propogated by cuttings rather than by seed, so the plants are all alike, and the genetic diversity found in the native seed bank is diminished. This diminishment is a threat to the plant’s ultimate survival.  Rather than nativars, the best action is to plant seed-propagated natives from as close to home as possible.

Places to get natives in our area are the New England Wildflower Association’s Nasami Farm in Whately (http://www.newfs.org/visit/nasami-farm), Tripple Brook Farm (http://www.tripplebrookfarm.com/tbf/man/general/about_us.shtml),  and Helia Nursery in Housatonic (http://helianativenursery.com/, They are in transition, so inquire).

If you buy elsewhere, be wary of plants labelled “native.” Ask the retailer whether the plant is native to the Connecticut River Valley and has been propogated from seed rather than by grafting or cuttings. Also ask whether any neonicotoids have been applied to the soil–these are insecticides taken up by the plant, and they poison insects that feed on the plant.
