Design with this plant

Overview

Echium pininana, or Tree Echium, is a biennial or short-lived perennial, adding architectural grandeur to gardens. Towering up to 13-15 feet, it sports a dense spike of small blue or violet flowers, a magnet for pollinators. Best in USDA zones 9-11, it thrives in full sun and well-drained soil. Drought-tolerant once established, it's advised to shelter from strong winds. Not cold-hardy, it requires frost protection in cooler climates.
