Taxonomic Rank: Magnoliopsida: Scrophulariales: Scrophulariaceae
Native Range: Danube region and Greece (BAIL);

Digitalis lanata is perennial herbaceous plant that grows from 2-5 ft. (0.6-1.5 m) tall. It is a species of foxglove. There are wooly hairs on the purple tinged stem. D. lanata is native to temperate Asia and much of Europe.
The first year a rosette of leaves forms. The alternate leaves are simple and oblong with an acute apex. They are a medium green color and pubescent with white hairs underneath.
The single flowering stem is usually produced in the second year. The tubular bell shaped flowers ascend up the stem. They have a creamy-white color and purplish-brown netting as well as a long broad lip. The entire inflorescence is pubescent.
The fruits of D. lanata are oval pods. The pods have small hooks that can easily attach to animal fur. Each pod contains many seeds.
Ecological Threat
D. lanata has been seen to invade open sunny roadsides, yards, grasslands, river bluffs and forest edges where it displaces native vegetation. It tolerates a wide range of sites and conditions. Caution: All parts of D. lanata are highly toxic to humans, livestock and wildlife. Ingestion of even a small amount may prove fatal. Prolonged exposure to bare skin can also produce adverse reactions.
