Allium obliquum
Allium obliquum
Allium obliquum is a cold-hardy ornamental onion native to Central Asian steppes that grows well in temperate gardens with partial shade to full sun. It requires little maintenance once established and benefits from well-draining soil; allow the surface to dry slightly between waterings. The attractive upright foliage and globe-shaped flower heads make it a subtle but charming addition to borders and rock gardens.
