- Description
-
Echium is a genus of about 70 plants that are native to Europe, N. Africa and Central Asia and are in the Boraginaceae (or Forget-me-not) family. These plants have naturalized in areas as South Africa, Australia, New Zealand and parts of South America and the United States. In some counties, they have become invasive.
Echiums can be perennial, evergreen or semievergreen. They can be shrubs to short-lived perennials that die after flowering. Most types have deep tap roots to survive drought, narrow thick hairy leaves and tall showy spikes of blue, purple, pink, red or white tubular flowers that attract hummingbirds and bees.
These plants prefer well-drained soils in full sun. They are drought and deer tolerant and most survive on neglect. If you live in a cold winter climate, some types can be grown in a pot and brought indoors for winter.
Insects, Diseases, and Other Plant Problems: No significant problems.
