Grown for striking form and flower clusters. All do well in dry, poor soil but need good drainage. All are excellent for seacoast gardens. Flowers attract bees. Give little or no water in mild-summer climates, weekly irrigation during summer in hotter areas.

Echium wildpretii

Striking oddity fromthe Canary Islands spends itsfirst year as an attractive, roundish mass of long, narrow leaves covered with silvery gray hairs. It starts to grow the second year. By mid- or late spring, it forms a 6–10-ft.-tall column 1 ft. or more in diameter, made up of manylittle rose to rose-red flowers.When all flowers have faded, the plant dies, leaving behind many seeds. The resulting seedlings may grow and bloom the next year if they are not hoed out.
