Allium giganteum
Allium giganteum or ornamental onion is a striking perennial bulbous plant with a narrow, tall upright shape and strap-shaped, gray-green aromatic leaves. From May to July, this plant blooms with countless purple-pink flowers grouped in large, almost spherical flower heads on high vertical stems. Allium prefers a position in full sun or partial shade, does well in almost any soil type and requires little maintenance. This ornamental onion is very hardy, drought tolerant and resistant to air pollution.
