On a late afternoon in May, Pam Durrant, her husband David, and I watched a Baltimore oriole adding to its nest in a sugar maple overhanging the stone patio at their farm.
The oriole was tucking a long piece of grass into the nest. David noted that the long grass was essential for the nest but couldn’t be procured in a closely manicured yard where the grass would be kept too short. As many Harvard Press readers know the Durrants from their column on birding, this seemed like a perfect transition to our topic, native plants.

Pam Durrant has worked as one half of Durrant Design in Harvard since the 1970s, as well as having served for many years on the boards of organizations such as the Harvard Conservation Trust and Native Plant Trust. She also grows organically almost all of their year’s supply of vegetables. Durrant is an excellent resource on native plants, although she says she started out from a background of general landscape design. “I’m a plant person—I just like plants,” she emphasized while explaining that she thinks of herself as someone who continually learns about native plants rather than as an expert.
Although reluctant to claim expertise, Pam readily shares her knowledge—for example, by leading guided walks on conservation land for the Garden Club of Harvard. In fact, any conversation with Pam about native plants is punctuated by getting close to the subjects, turning over a leaf, or pushing foliage aside to check out a stem.
She notes that when readers are out walking on conservation land or along the road, in early June, they may observe the following native plants in various stages of bloom: wild geraniums, Solomon’s seal, daisy fleabane, wild strawberry, mapleleaf viburnum (in shady oak woods), arrowwood viburnum (at the edge of woods), and silky dogwood, among others. She recommends iNaturalist to help identify a plant and encourages readers to do a little research to understand the plant.
Hiking the Appalachian Trail in Maine in the 1980s—in particular, observing the high-elevation alpine-zone grassland in the Mahoosuc Range—struck a chord with Pam that continues to resonate into the present. She notes how critical it is to observe native plants growing in their habitats in order to understand how they may look and behave in your garden; additionally, readers may find inspiration from the work of talented horticulturalists displayed at Garden in the Woods in Framingham and Norcross Wildlife Sanctuary in Wales. Besides appreciating their beauty, Pam notes the environmental benefits of native plants—for example, they sustain more diverse birds and pollinators than do non-native ornamentals and are better adapted to their environments, and so use less water and grow well organically.
Learning how to identify native plants growing naturally in your yard or public spaces takes work, but the art of observation is rewarding. Pam explained that, along with former Bromfield science teacher and botany Ph.D. Dorothy Andrews and conservationist Bob Reed, she used to go out weekly in all weather, armed with Newcomb’s Wildflower Guide. Their group worked through the printed dichotomous keys to categorize plant characteristics and arrive at identifications, while observing tree buds in the winter and blooms in the growing season. Pam also took classes through the Native Plant Trust, and has worked as one of its plant conservation volunteers who monitor rare plant populations across the Northeast.
There is no end to what you can learn about plants, Pam emphasizes. “It is good to understand what you don’t know as well as what you do know.”

Pam Durrant’s tips for bringing native plants into your yard
1
Think about what “native” means and why we value it. The USDA’s National Resources Conservation Service considers a native to be “a plant that is a part of the balance of nature that has developed over hundreds or thousands of years in a particular region or ecosystem.” It also notes that “native” should “always be used with a geographic qualifier (that is, native to New England).” Pam reminds us that home gardeners are almost always working on disturbed land: “I like to integrate native plants in my garden, but I also understand I live on a landscape that has been farmed for at least a couple hundred years. I understand that there’s not a lot of natural landscape (to start from).”.

Know how your native plants are grown. Native plants sold in bulk at many chain stores are typically produced as clones of a parent plant, rather than through sexual reproduction (pollination and seed formation), which selects for environmental adaptation over time. If growing from seed, gardeners should know where the retailer got the seeds and seek seeds from the same region in which they will be planted. Maine Wild Seed Project and Native Plant Trust, for example, provide clear information about seed provenance. Another issue with big box stores and some large retailers is the use of neonicotinoids, colloquially referred to as neonics. Neonics are systemic pesticides taken up by the plant and transported throughout it. They are toxic to insects. Gardeners should ask if neonics have been used.

Aesthetic considerations foundational to garden design can well accommodate native plants in most cases. Many gardeners will choose native plants to fill existing spots in their gardens, perhaps taking the place of non-native ornamentals—the basic layout does not have to be created from scratch but rather can emerge from an ornamental design. With this in mind, it’s also OK to admit that sometimes there is simply not a native plant that will work in the desired spot. (Pam declares that she is not going to give up her peonies, although she has invested in finding and planting species peonies rather than the less natural hybrids sold at many garden stores.) New aesthetic sensibilities will emerge, of course, with attention to natives—close-cropped lawns and hybrid, double flowers (blooms that have a mutation to create a many-petalled but sterile flower) may no longer look so attractive from the natural gardening perspective.

“Editing” is a great technique for naturalizing less cultivated areas, such as an old pasture, a patch of grass lawn, or an overly cleared forest edge. Native plants will not grow equally well everywhere simply because they are native to a region, so it’s best to work with what you have. Learning to identify what at first appear to be “weeds” in the space set aside for naturalizing is helpful. Encourage desirable native plants to thrive by weeding around them and giving them the space to grow; disperse their seeds by hand to help them spread (for example, wild geranium seeds should be sowed while still fresh rather than dried). Invasive plants may be removed—often a slow and painstaking process, but one that shows significant results over several seasons.
