Foxglove Facts and Information
Foxglove is a biennial plant that grows in Zones 3-8. It reaches heights of 3-6’ and up to 24” wide with an upright growth pattern. Foxgloves prefer full sun to partial shade from the afternoon sun. Provide fertile, well-drained soil with pH of 5.5-7.0. Tall spikes of purple, pink, or white flowers appear in early summer. Plant in them in cottage gardens, a mixed perennial border, along fence rows, and in the bright woodland garden.
Companion plants for foxglove include: ‘Fire King’ yarrow, apothecary rose, ‘The Rocket’ ligularia, and ‘Stargazer’ Lily.
Plant foxglove at least 18” apart in spring or fall in fertile soil that is high in organic matter. After planting, water deeply and add 3” of mulch around, but not touching, the plants. Apply slow-release granular plant food at the time of planting or begin using water soluble plant food 3 weeks after planting in spring.
Water deeply whenever the soil becomes dry. Remove flower stalks after blooms have faded or leave erect long enough for seeds to drop if self-seeding is desired. If plants do not self-seed in the landscape, plan to replace them every year or two with container stock.
As mentioned, foxglove will self-seed in the landscape, but seeds can be started indoors. This is done by sprinkling seeds over the soil mix and leave them exposed to the light, do not cover. Thoroughly moisten and keep moist, not soggy, until seeds germinate. Germination occurs in 5-10 days after sowing. After germination, reduce the temperature to 55-60 degrees.
Foxglove Pests and Diseases
Diseases often include Southern blight, anthracnose and fungal leaf spots.
