- Description
-
Pencil Flower is a native perennial wildflower in the legume family found in central and eastern USA in dry woods, fields and thickets. It is found throughout NC. The plant grows .5 to 1.5 feet tall and the yellow pea-like flowers bloom from late spring to fall, but rather sparsely. Bees pollinate the flowers and deer and rabbits will browse the leaves. There is some variation in the leaves and flowers throughout its range.
This plant prefers acidic somewhat poor soils, due to less competition, in full sun to partial shade. It is generally not used in cultivation and is hard to find but could be grown in naturalized areas.
