3/31/2026- April Native Plant Highlight: Twinleaf (Jeffersonia diphylla)

Twinleaf (Jeffersonia diphylla) is a spring ephemeral wildflower native to moist deciduous forests of eastern North America — and the namesake of our own Twinleaf Book & Gift Shop. Its most distinctive feature is its deeply divided, two-lobed leaf, which gives the plant its common name. Delicate white, eight-petaled flowers appear in early spring on leafless stalks just 8 inches tall. The delicate petals drop easily – they can be particularly ephemeral because of a spring breeze or gust of wind; however, unlike most of their flowered companions, twinleaf foliage remains green throughout the growing season.

The twinleaf plant was formally named in 1792 by Benjamin Smith Barton in honor of Thomas Jefferson and was later cultivated at Monticello, reflecting its place in early American botanical study. Yet long before its European classification, Indigenous peoples of this region held extensive knowledge of the plant and its uses. Although written ethnobotanical records are limited, Indigenous communities such as the Lenape of the Delaware River Valley and the Haudenosaunee of the Iroquois Confederacy have prepared parts of the plant for medicinal purposes, including treatments for internal conditions such as digestive issues. Recognizing this history underscores the Twinleaf’s story that is rooted not only in early American horticulture science but also in generations of Indigenous stewardship and ecological knowledge.

In the garden, twinleaf thrives in dappled shade beneath deciduous trees. It pairs beautifully with May-apple (Podophyllum peltatum), rue anemone (Thalictrum thalictroides), wild ginger (Asarum canadense) and native ferns. It grows and spreads very slowly, hence the propagation challenge. Fortunately, it has no known serious pest problems.
