Plant Details:

Plant Type: Perennial

Plant Description: A large ornamental onion, 'Globemaster" blooms in late-spring to early summer with large, round violet lavender flower blusters. It's tall sturdy stems withstand wind and rain to keep the blooms aloft for bees and butterflies alike. It takes advantage of the wet temperatures of spring, fading as the drought of summer comes.

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.
