Cynara cardunculus
cardoon
This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.
- Position: full sun
- Soil: fertile, well-drained soil
- Rate of growth: average
- Flowering period: June to September
- Hardiness: fully hardy
The majestic, purple, thistle-like, honey-scented flowers of this stately cardoon are held above clumps of magnificent, deeply cut, silvery-green leaves. Given plenty of space, this perennial makes an eye-catching focal point for a large, sunny, mixed or herbaceous border, or potager, sheltered from strong winds. The flowers are particularly valuable for use in fresh or dried flower arrangements - Garden care: Avoid the temptation to remove the faded flower-heads in autumn as they provide interest in the winter garden. Where temperatures fall below -15°C (5°F) protect the crown of the plant with a dry, straw mulch.
