'Schubertii'
Allium
Allium schubertii, commonly known as tumbleweed onion, reaches 12 to 24 inches tall, featuring 9 to 12 inch spherical flower heads packed with loose, star-shaped rose-purple florets. Blooming in late spring to early summer, its dramatic, firework-like blooms create a striking focal point. As the seed heads dry, they detach and roll across the garden, dispersing seeds as they go—hence the name tumbleweed onion. Thriving in full sun and well-drained soil, it is drought-tolerant, deer-resistant, and attracts pollinators. Its strap-shaped blue-green foliage withers as the flowers emerge, allowing the blooms to take center stage. Ideal for borders, rock gardens, and mixed plantings.
