Description
Add bold color and height to your garden with Allium Rosenbachianum, a striking ornamental onion with large, round clusters of reddish-purple, star-shaped flowers. Growing 39–47 inches tall, Allium Rosenbachianum creates a strong vertical accent when planted among low-growing perennials or annuals. The 4-inch flower heads bloom in late spring and attract bees and butterflies to the garden. This hardy bulb thrives in full sun to partial shade and grows well in USDA hardiness zones 4–8. It is also deer resistant and drought tolerant once established, making it an easy-care choice for beds, borders, cottage gardens, and natural-style landscapes. Plant bulbs 5 inches deep in well-drained soil, then allow the foliage to fade naturally after blooming.
