Digitalis obscura
''Digitalis obscura'' is a flowering plant, commonly known as the Sunset Foxglove or Willow-leaved Foxglove. It is native to regions in Spain and Africa, but can be grown as an ornamental flower around the world. It is a perennial woody plant belonging to the family Plantaginaceae. (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.) The Sunset Foxglove is similar to many of the foxglove species in its high toxicity and medicinal use as a source for the heart-regulating drug digitalis. Its strikingly distinctive amber- to copper-colored flowers give the species its name and help distinguish it from other members of the genus.
==Description and habitat==
''Digitalis obscura'' is native to eastern to southern Spain and northern Africa. It occurs in both the mountains and the lowlands near the coast. However, it can be grown in many non-native areas as an ornamental plant. ''Digitalis obscura'' naturally grows well in dry climates and in high altitudes. Unlike many other foxgloves, it is drought-tolerant when it is deeply rooted and established. It thrives in average, well-drained soil with pH levels of 5.8–7.2. It may die if left in wet soil over winter. ''Digitalis obscura'' grows in either full or partial sun. It blooms during late spring from May to June and spreads over the ground about 0.75–1.5 feet. Once established, it is perennial and grows at a rather moderate to fast pace. It is non-invasive and attracts hummingbirds. It is naturally resistant to deer and rabbits.〔(【引用サイトリンク】url=http://plantlust.com/plants/digitalis-obscura/ )〕
