About this seed
Allium atropurpureum is an ornamental allium with deep purple-red flower heads in late spring to early summer, 0.5–1 m tall, grown in full sun. It is listed here as "scallion purple flower"; it is grown for its blooms, not as a bunching onion.
Also known as: Very-dark purple allium (RHS), Ornamental onion, Flowering onion, Zierlauch (German), Ail d'ornement (French), Ajo ornamental (Spanish).
What the plant becomes
- Height 0.5–1 m and spread up to about 0.5 m.
- Flower colour: deep purple-red.
- Flowering: late spring into early summer.
Where it grows
The Royal Horticultural Society lists full sun and chalk, clay, loam or sand soil, and rates it hardy to roughly -15 to -10 °C (its H5 rating), so it overwinters in most of the UK. Choose a spot that drains well; allium roots dislike standing water.
What we cannot tell you yet
We have no sourced germination temperature, emergence time or sowing depth for this species, and we do not state any. Sow into a well-drained mix, keep it lightly moist and give seedlings full sun once they are up. Seed-raised alliums can differ from one another and take time to reach flowering size.
FAQ
Is this the scallion used in cooking?
No. Scallions are a different allium. This card describes Allium atropurpureum as an ornamental, and we make no cooking claims.
When will it flower?
Established plants flower in late spring into early summer; seedlings need time to reach flowering size.
