Features

notes

Allium Purple Sensation is a mid-height variety of ornamental onion, a cottage garden staple, which features deep violet, star-shaped flowers in densely packed globe clusters on tall sturdy stems from mid-May. Great for adding elevated interest to a border.

Insights

Attractive to butterflies and bees, this hardy perennial bulb has a long flowering season. Plant in the middle of the border, so the umbrels can grow through other foliage such as paeonies; it can take over from tulips. Also ideally suited to gravel gardens or prairie style planting.
