Alliums prefer full sun and well-drained soil.
The large Allium genus is characterized by small six-petaled florets held in umbels—large or small, loose or tight. Sweet-smelling blooms make great fresh cutflowers or dried winter arrangements whether you cut them before or after the green seed pods form.
The same genus as all edible onions, garlic and chives. Most repel slithery, winged and legged pests—including deer, and only when crushed do they smell like onion.
