Monrovia® Windy City Ornamental Onion is a clumping herbaceous perennial with spreading dark grass-like foliage. Sturdy upright stems sport fragrant global clusters of rich lavender flowers at the ends that bloom in mid summer. Grows best with light afternoon shade in the South and dry to medium well-drained soils. When crushed the foliage smells like onion. Windy City is near-sterile.
