Description
The ornamental garlic produces spherical, violet flower heads on tall, bare stems in June, resembling lanterns hovering above the bed. The dried seed heads remain decorative into the fall, and bees are attracted to the nectar-rich individual flowers.
Care instructions
Plant the large bulbs in September or October at a depth of about 20 cm in well‑drained, sunny soil—deeper planting yields a sturdier stem. Water sparingly, as the plant does not tolerate waterlogging. Allow the foliage, which often yellowes before flowering, to die back naturally; plant low‑growing perennials in front to conceal the withering leaves.
