Sow seeds of annuals species in spring; sow perennial and biennial species in summer. Root semi-ripe cuttings of shrubby perennials in midsummer.
Echium grows best with full sun, and thrives in areas with hot summers. Species are drought tolerant, but cannot withstand temperatures below 30ºF. Where hardy, grow Echium in an annual, mixed, or herbaceous border. They also make good container plants. Elsewhere, raise Echium indoors.
Flowers are borne from spring to summer. They attract bees, butterflies, and birds.
Soil that is too rich will hinder flower formation.
Soil and Irrigation:
Outdoors, Echium does well with poor, dry soils. For indoor plants, use a standard soil-based potting mix. Water freely during the growing season; water sparingly in winter.
Plants should be cut back hard before winter.
Slugs are known to attack young growth. Other pests include whiteflies and spider mites.
