Some flowers conjure up visions of an English cottage garden and foxglove is one of them. The ones you see in this vision are a lovely shade of strawberry pink and unfortunately are biennials and disappear after blooming. So much for that vision. But there is a foxglove that is perennial and has the characteristics that give foxgloves their charm so perhaps you should give them consideration.
Yellow foxglove is easy to grow and will provide a long season of bloom if deadheaded. It is easy to start from seed or to buy seedlings by mail order. They are very forgiving in regard to soil but they will thrive in a good moist, humusy, slightly acid garden soil. They do well in partial shade here in North Carolina but do well in full sun in a cooler climate. To provide all season bloom cut off the flowering stalks at their base when only a few flowers remain; new flower stalks will develop very quickly.
Yellow Foxglove with its numerous flower spikes of 3’ is a great addition to a woodland garden or the back of a perennial border. In both sites it will be a good choice for adding color, brightness, and vertical accent. There is something about a foxglove that dominates the scene!
