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.
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.
