Echium
|
This genus of about 40 mildly poisonous shrubs, annuals and biennials in the borage family is native to the Mediterranean region. Several species are grown for their spectacular spikes of blue, purple or pink flowers, produced in late spring and summer. Most of the shrubby species grow in mountainous areas in quite austere conditions. |
CULTIVATION: Echiums are best treated as in nature, with only moderate amounts of fertilizer and water. They are suited to coastal conditions and a position in full sun. They will tolerate only light frosts. Propagation is usually from seed, but cuttings may be taken in spring or summer. In mild climates they self-seed quite readily. |

Heliotropium
|
Belonging to the borage family, Boraginaceae, this is a genus of approximately 250 species, mainly evergreen shrubs, from Central America and temperate South America. Some are locally important medicinally and others are significant ornamentals. |
CULTIVATION: Most prefer fertile free-draining soils, summer moisture and shelter from cold. Full sun to filtered light is their favored habitat. Where frosts occur, the most sheltered position in the garden must be selected. Prune moderately immediately after flowering to encourage new shoots. Propagate from soft-tip cuttings in spring or summer or half-hardened cuttings in autumn to winter in a warm and moist situation. |
