Imposing blooms come highly recommended by our Dutch garden experts. The perfect spheres of Persian Blue Allium, also known as Purple Sensation Allium, are actually hundreds of clustered, star-shaped, purple-blue florets. They create a dazzling effect as they appear to rise almost overnight, adding a unique flower color to the landscape. And like all alliums, they drive rodents, aphids and even slugs away from the garden! Alliums are not available in ID and WA.
