• Excellent deer and pest resistance, making it ideal for problem areas
• Long-lasting blooms that maintain visual interest even after flowering
• Drought-tolerant once established, reducing maintenance requirements
• Attracts beneficial pollinators including bees and butterflies

The architectural quality of these blooms makes them perfect for modern landscape designs, cottage gardens, and naturalistic plantings.

Planting and Growing Information

Plant Allium Rosenbachianum bulbs in fall, approximately 4-6 inches deep and 6-8 inches apart in well-drained soil. These versatile bulbs thrive in full sun to partial shade conditions and are suitable for USDA hardiness zones 4-8. After the spectacular late spring flowering period, allow foliage to die back naturally to ensure energy returns to the bulb for next season's display. The dried flower heads provide winter interest and can remain standing through the colder months.
