Digitalis purpurea. Tubular, nodding flowers are often speckled and tumble on husky spires to 2m (6') tall. They are welcome in the border, woodland, or whenever they randomly self-sow. Foxglove flowers late spring to summer, and may flower again from the tops of the stems in late summer or fall. Sow Foxgloves Digitalis seeds indoors in late winter for flowers the first year. Transplant to naturalize at the back of the border. Foxgloves thrive in moist, shady areas, but can stand full sun if they are kept watered. Each plant produces thousands of tiny seeds - to avoid self sowing, cut the stalks down as soon as flowering has finished.
All parts of the Foxglove plant are poisonous.
These majestic yet unpretentious biennial plants are perfect for shady spots and cottage gardens. The flowers are highly attractive to bees and other pollinators. Continue reading below for some tips on how to grow foxgloves from seed.
Season & Zone
Exposure: Full sun to shade
Zone: Hardy to Zone 4
Direct sow outdoors after last frost for flowers the following year. In mild winter areas, direct sow in autumn as well. For flowers the first year, sow indoors very early, in December or January for transplanting 2-3 weeks before last frost. Seeds take 14-21 days to germinate. If starting indoors, provide bright light and a soil temperature of 15-18°C (60-65°F).
Sow on the surface. Space or transplant 45-60cm (18-24″) apart.
Water plants deeply on a regular basis. Cut off finished flowering stems to prevent self-sowing. Otherwise, expect foxgloves to naturalize around your garden. Foxgloves will languish in periods of heat and drought, so provide extra moisture during those times. If allowed to go to seed, foxgloves tend to self sow for several generations.
