Although a rare American wildflower, Addison's leather flower adapts well to garden culture and proves to be easy to grow. Its crowning glory are the lavender-purple and creamy white flowers that occur in spring's warmth. This herbaceous perennial is native only to four counties in west-central Virginia, in the dry woodlands on non-acidic soils.
The plant forms a clump with multiple erect to sprawling stems. In some cases the stems twine around nearby plants to reach upward to the light. In mid-spring to early summer, tops of stems bear a singular, bell-shaped flower that is bicolored and nodding. The petal-like sepals are leathery in texture. The blossom ranges from rose-violet to plum or lavender-purple, and edged in creamy ivory or white. The large, bluntly oval green leaves occur in pairs and make an attractive background to the upright flower stems. The ensuing seed heads are golden tan and spidery in silhouette. Often Addison's leather flower will again rebloom in late summer or early fall. Frost kills the plant back to the ground annually.
Only grow this wildflower from seed or from container-grown plants ethically and legally harvested from the wild. Addison's leather flower grows well in a non-acidic, well-drained but fertile soil. It prospers in nearly full sun to light shade. The soil should be moist, but seasonally dry soils are tolerated, especially if plants are shaded in the hottest part of the day. Use it as a clumping groundcover or accent in a woodland garden or shady rock garden.
