Summary

Digitalis grandiflora, commonly known as Yellow Foxglove, is a perennial herb that is semi-evergreen in mild climates and native to open woods and forest margins across Europe and Western Asia. It forms a rosette of glossy green, veined leaves from a short rootstock with fibrous roots. The flowering stems of D. grandiflora can reach heights of 70–120 cm (28–47 in), showcasing pale yellow, bell-shaped flowers that are spaced out along the stem, each 3–4 cm (1–2 in) long with distinctive netted brown markings inside. The flowers are particularly showy due to their size and the contrast of the markings, blooming in the wild from June to July.

Yellow Foxglove is valued for its stately flower spikes and its ability to thrive in partially shaded conditions, making it a favored choice for woodland gardens, shaded borders, and cottage gardens. It has earned the Royal Horticultural Society’s Award of Garden Merit, indicating its excellence for garden use. This plant is winter hardy in USDA zones 3 to 8 and prefers moisture-retentive, well-drained, organic soils. While it typically blooms from June to August in Germany, in North America, the flowering season varies, with May to June in Missouri and June to July in Ohio, generally lasting eight weeks. Yellow Foxglove requires consistent moisture but is relatively low maintenance once established. It is important to note that all parts of the plant are toxic if ingested, and it should be handled with care to avoid skin irritation.CC BY-SA 4.0
