Step-by-Step Growing Guide
Foxglove (Digitalis purpurea) is a stately biennial (occasionally perennial) producing tall 3–5 foot flower spikes in its second year. It prefers humus-rich, well-drained, slightly acidic soil with a pH of 5.5–6.5. Start seeds in early summer for bloom the following year, or in late winter indoors for late summer transplanting. Seeds need light to germinate — press onto the surface of moist seed-starting mix and do not cover. Thin or transplant to 18–24 inches apart. Foxglove thrives in partial shade — it is a woodland edge plant in nature and tolerates more shade than most flowering plants. Water consistently, keeping soil moist but never waterlogged. Apply a balanced fertilizer in spring of the second year when rosettes begin growing rapidly toward their flower spike. After flowering, the plant typically dies, but allows some plants to self-seed prolifically for a continuation of the colony. Deadhead spent spikes to promote secondary smaller side spikes.
