Foxglove

Digitalis purpurea

Foxgloves are a native British wildflower that has earned its place in cultivated gardens through sheer dramatic beauty. Their tall spikes of tubular, spotted flowers in June and July are a classic feature of cottage gardens and woodland edges. As biennials, they form a rosette of leaves in their first year and flower in their second, after which the plant dies — but self-seeding is so prolific that once you have foxgloves, you'll always have foxgloves. They thrive in partial shade and moist, humus-rich soil, making them perfect for planting under trees and in the back of borders. The native species is purple-pink, but there are beautiful cultivated forms in white, apricot, and yellow. All parts of the plant are highly toxic — the source of the heart drug digitalis — so exercise caution around children and pets. Bumblebees adore foxgloves, crawling deep into the tubular flowers for nectar, emerging with pollen-dusted backs.

Expected Yield

Each plant produces one main spike and several side spikes; self-seeds prolifically.

Growing Tips

Toxic if ingested

Pruning Foxglove

Cut the main spike just below the lowest flowers once it fades and side spikes will often follow. Leave one or two spikes to set seed if you want self-sown plants for future years.

Common Problems with Foxglove

No flowers in first year

Foxgloves are biennial — they only flower in their second year. Be patient, or buy second-year plants.

Self-seeding too aggressively

Remove flower spikes before seed disperses if you want to control spread.

Rust

Orange spots on leaves. Remove affected leaves and improve air circulation.

Foxglove: common questions
