Ornamental Onion

Allium aflatunense

Plant Details:

Plant Type: Perennial
Plant Family: Liliaceae
Plant Description: This summer blooming onion produces large purple spheres in mid to late-spring. Long, strap-like leaves are green and fade shortly after blooming. Its growth timing avoids the extremes of summer heat, thus avoiding drought.

Maintenance:

Maintenance Type: Perennial - Herbaceous
Plant Care: Perennial - Herbaceous (soft-stemmed plants that die back in winter and regrow in spring): Remove spent blooms to promote rebloom later. Some plants tend to flop over after the first bloom and attempt to regrow from the base; in these cases, the old stems can be cut away in summer. As plants become dormant in the fall, remove dead leaves and stems.
