About
Allium 'Bizar' is a bulbous perennial that features slender, linear foliage in the spring, which then dies back during the summer months. It boasts narrow, upright stems reaching up to 1 meter in height, topped with clusters of dark red bulbils instead of traditional flowers. These bulbils give rise to additional delicate, curved or twisted stems that bear small bulbils at their tips, blooming in the spring.
