Providing striking color and architectural height to borders, Digitalis ferruginea (Rusty Foxglove) is an eye-catching biennial or short-lived perennial boasting tall spikes of pendulous, funnel-shaped, creamy to pale golden-brown flowers with rusty interior veining. Blooming in late spring to early summer, they rise from a basal rosette of dark green, deeply veined, semi-evergreen leaves. They are attractive to hummingbirds, which hover near the tubular blossoms and to birds, which will flock to the seedheads in the fall. This architectural plant naturalizes well as it self-sows profusely, creating lovely colonies in the landscape. A wonderful addition to the herbaceous border.
