Ornamental onion with large round lavender-purple flower heads on upright stems

Light

Full sun.

Water

Water weekly the first season; after that it handles dry spells.

Planting and soil

Plant in spring or early fall, crown at soil level.

Feeding

None needed.

Pruning

Leave seed heads for winter interest or cut them to stop self-sowing. Cut foliage back in late fall or spring.

Through the year

Foliage up in spring, flowers July to August, seed heads into fall.

If something's off

Wet soil rots the bulbs. Alliums are toxic to dogs and cats.

Plays well with

Plant it with friends.
