- 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 semi-evergreen. They can be shrubs to short-lived perennials that die after flowering. Two years of growth must be completed before flowering will take place. Although some varieties will die after flowering, they will provide enough seed for the next year.
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.
Pruning is not necessary, however, a trim in the fall as well as the removal of the old flower spikes will give you a neater appearance while preventing the plant from becoming straggly.
Insects, Diseases, and Other Plant Problems: No significant problems. Shelter from strong winds is advisable.
