Avalanche White Sun Daisy

Osteospermum hybrid 'Avalanche' PP #22,705

Huge, dazzling white flowers are held over glistening, evergreen foliage. Not just another white daisy, this selection is hardier, more disease resistant and vigorous than other selections, and it does not set seeds, meaning it blooms nearly non-stop! The flowers close at night, revealing a metallic reverse that shines in moonlight. Perfect for a rock garden, border or containers. A Plant Select® award winner.
