How to Grow Echium – Pride of Madeira

Sharing is caring!

Echium — commonly called Pride of Madeira — is a genus of showy perennials and biennials native to the Mediterranean. They bear panicles of bell-shaped flowers in shades of blue, lavender, purple, rose, or white. Where not hardy Echium can be grown as annual. Echiums are colorful additions to annual, mixed, or herbaceous borders. They can also be grown in containers.

Two members of the Echium genus are often grown in gardens. Echium candicans–commonly called Pride of Madeira–is a woody-based biennial that bears dense cylindrical panicles to 12 inches (30cm) long of narrowly funnel-shaped white or bluish flowers from spring to summer. It grows 5 to 8 feet tall (1.5-2.5m). Echium vulgare–commonly called viper’s bugloss–grows just 12 to 18 inches (30-45cm) tall and bears bell-shaped flowers in shades of blue, lavender, purple, rose, or white; the flowers are just a half-inch across.

Echiums can be set in the garden or seeds sown as soon as the danger of frost is past. They will begin flowering as early as three months after sowing. In frost-free regions, seeds can be sown outdoors in the fall as well as in the spring. Fall-sown seeds will blossom at least a month earlier than those started in the spring.
