Synonym: Digitalis aurea, Digitalis guellii, Digitalis intermedia, Digitalis nutans
Habitat: Digitalis lutea is native to Europe. It grows in woodlands, hedgerows and uncultivated fields on siliceous soils.
Digitalis lutea is a short-lived perennial plant. It grows 0.6 m (2ft) by 0.3 m (1ft in). The leaves are oblong to inversely lance-shaped, veined, glossy, dark green and, in early to midsummer, upright stems bearing slender racemes of narrow, tubular, pale yellow flowers, hairy inside.The flowers are yellow, with brown dots on the inside of the corolla. Flowers are borne beginning in late spring, then sporadically throughout the summer and fall. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Bees.
Like many foxgloves, this plant is often grown in gardens, where it readily self-sows and can become weedy.
An easily grown plant, succeeding in ordinary garden soil, especially if it is rich in organic matter. It also succeeds in dry soils and, once established, is drought tolerant. It prefers semi-shade but succeeds in full sun if the soil is moist. Members of this genus are rarely if ever troubled by browsing deer or rabbits. The yellow foxglove is a good companion plant, stimulating the growth of nearby plants. Root crops grown near to this plant will store better.
Seed – surface sow early spring in a cold frame. The seed usually germinates in 2 – 4 weeks at 20°c. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer.
Cardiac; Diuretic; Stimulant; Tonic.
Yellow foxglove is little used in herbal medicine but is in fact a less toxic alternative to the purple and woolly foxgloves (D. purpurea and D. lanata) which are widely used in the treatment of heart complaints. The yellow foxglove has similar medical actions, but its alkaloids are more readily metabolized and flushed out of the body. The leaves are cardiac, strongly diuretic, stimulant and tonic. They are used in the treatment of a weakened or failing heart, increasing the strength of contraction, slowing and steadying the heart rate and lowering blood pressure by strongly stimulating the flow of urine – which reduces overall blood volume. The leaves of plants in their second year of growth are harvested in the summer and dried for later use. This remedy should be used with caution and only under the supervision of a qualified practitioner, excessive doses can prove fatal. See also the notes above on toxicity.
Other Uses: Preservative……..An infusion of the plant added to the water in the vase will prolong the life of cut flowers. When grown near root crops the roots will store better.
Known Hazards :All parts of the plant are poisonous. The plant is less dangerous that the common foxglove (D. purpurea) since its effects are not cumulative.
