Ornamental onions are grown for their globe-shaped flower heads that remain attractive once dried as well in flower.

Allium stipitatum is a beautiful allium, bearing tight balls of pink-purple flowers on slender stems, in early summer. The long, linear foliage of Allium stipitatum dies back before the blooms appear. It's perfect for growing in a mixed herbacesous border and makes an excellent cut flower.

Grow Allium stipitatum in moist but well-drained soil in full sun. Leave seedheads in place over winter to provide winter interest. Mulch annually with well-rotted manure or compost.
