Digitalis grandiflora

Digitalis grandiflora, the yellow foxglove, [1] [2] big-flowered foxglove, or large yellow foxglove, is a species of flowering plant in the genus Digitalis, family Plantaginaceae (formerly Scrophulariaceae). It is native to southern Europe and Asia. In mountains it grows on warm, bushy slopes or areas left after logging. The Latin specific epithet grandiflora means “large flowered”. [3]

Description

It is a herbaceous perennial growing from a short rootstock with fibrous roots. [4] D. grandiflora has glossy green, veined leaves, whose flowering stem can reach a height of 70–120 cm (28–47 in). The pale yellow bell-shaped flowers are spaced out on the stem, 3–4 cm (1–2 in) long and show a netted brown marking in their interior. [5] In the wild plants bloom in June and July. [6]

Cultivation

Digitalis grandiflora is long lived perennial, [6] it has gained the Royal Horticultural Society's Award of Garden Merit. [7] [8] It is winter hardy is USDA zones 3 to 8 and grows best in moisture retentive, but well drained, organic soils in part shade. [9] Cultivated plants in Germany bloom from June to August, in North America, flowering occurs from May to June in Missouri and from June to July in Ohio; with the typical bloom period lasting eight weeks. [6]

Cultivars

Hybrids

(Hybrid formula: Digitalis grandiflora Mill. × Digitalis purpurea L.).

Pharmacology

As the plant contains cardenolides, all parts are toxic. Its leaves contain 0.2% glycosides of the digitoxin-type and about 0,1% of the digoxin-type. Even so, the plant is not used in the production of cardiac glycosides.

<i>Digitalis purpurea</i> Toxic flowering plant in the family Plantaginaceae

Digitalis purpurea, the foxglove or common foxglove, is a poisonous species of flowering plant in the plantain family Plantaginaceae, native to and widespread throughout most of temperate Europe. It has also naturalised in parts of North America and some other temperate regions. The plant is a popular garden subject, with many cultivars available. It is the original source of the heart medicine digoxin. This biennial plant grows as a rosette of leaves in the first year after sowing, before flowering and then dying in the second year. It generally produces enough seeds, however, so that new plants will continue to grow in a garden setting.

Along with the other foxgloves it used to be placed in the figwort family, Scrophulariaceae; however, recent genetic research has moved the genus Digitalis to a larger family. It is similar to many of the foxglove species in its high toxicity and medicinal use as a source for the heart-regulating drug digoxin. Its strikingly distinctive amber- to copper-coloured flowers give the species its name and help distinguish it from other members of the genus.
