Giganteum – Pack of 3 or 10

• Flowers June/July
• 100cm +tall

Allium giganteum is one of the tallest and most impressive ornamental onions, producing large, spherical heads packed with tiny violet‑purple flowers. Rising on strong, upright stems in early summer, each globe adds bold structure and architectural height to borders. Long‑lasting, bee‑friendly, and reliably perennial in well‑drained soil, it brings a striking vertical accent to mixed plantings and looks superb both fresh and dried.
