Foxgloves (gouache style)

The common foxglove is a native British wildflower, found on woodland edges, heaths and hedge banks. Its tall spikes carry tubular flowers, usually purple-pink with spotted throats, though white forms are common in gardens. In 1785 the physician William Withering described its use in treating heart conditions, and heart drugs are still derived from foxgloves today. Every part of the plant is poisonous, so it's wise to wear gloves.

Most foxgloves are biennial. Sow seed between May and July, scattering it on the surface without covering, as it needs light to germinate. Pot the seedlings on and plant them out in autumn for flowers the following June and July. They're happiest in partial shade and humus-rich soil. Cutting the main spike after flowering can encourage smaller side spikes, but leave a few to set seed if you'd like them to spread. Self-sown seedlings can be moved in autumn or spring.

Tall pink and white foxglove spires stand at the edge of a border in this picture. That border edge is close to where they grow wild, on the margins between open ground and shade. The chosen moment shows the spires fully opened, when bumblebees are busiest among the bells.
