Helping You Become a More Successful Gardener

ALLIUM rosenbachianum 'Purple King'
This bulbous perennial is grown for its large round deep-purple umbels of star-shaped flower clusters with prominent, almost sparkly stamens. It blooms in mid to late spring atop tall leafless stems. The broad, strappy, shiny basal leaves wither as the flowers emerge. This ornamental onion is similar to and often confused with several other Central and West Asian alliums.
Plant the bulbs in fertile, well drained soil at a depth two to three times their diameter. This plant likes ample sun and dryish summer conditions. Lift and divide the bulbs only when they become crowded. Plant this stately beauty in groups in the mixed border, rock garden, or herb and vegetable garden. Plant extra to cut since this allium is long-lasting in a vase or even dried.
