Jeffersonia dubia

Description and general information

Jeffersonia dubia is a beautiful woodland plant from eastern Asia. (There are two species in the genus Jeffersonia; the other is Jeffersonia diphylla of eastern North America.) The most common form of J. dubia in North American gardens is a beautiful light lavender color, but there is a seed strain in cultivation which is a darker shade. Both are well worth growing.


Good woodland soil in decidous shade.

Bloom period

Blooms before the leaves come out on the deciduous trees.


Seed or division


Dry storage is fatal; sow seeds as soon as they are released.  They require a stratification period before they will germinate.


Plants are best dug after blooming, then divided.
