I planted a bed of pencil flower last fall. Doing great in part shade, nice form, pretty little flowers in the morning, looks great in mass planting. I'm going to plant a bed down on our hot, dry right of way and see how they do.

The Pencil Flower is actually in the bean family, Fabaceae, according to my Ozark Wildflowers book.


Editor's Note

Since 2004 the three subfamilies of Caesalpiniaceae, Mimosaceae, and Papilionaceae rather than Fabaceae

Wild Turkeys like the seed of this plant. This is also a host plant to Barred Yellow (Eurema daira) caterpillars. Extremely attractive plant.
