Prairie Onion

Prairie Onion (Allium stellatum) is a tough, drought-tolerant native bulb that brings beauty and resilience to sunny, dry landscapes. Works well to help fill a garden or naturalized area with charming, late-summer blooms that attract bees, butterflies, and other beneficial pollinators.

Each plant reaches 1–2 feet tall and is topped with round, pink-to-purple flower clusters made up of star-shaped blossoms. These ornamental blooms rise above narrow, grass-like leaves that release a mild onion scent when crushed. Prairie Onion is perfect for xeriscaping, rocky borders, or sandy prairie-style gardens, where it thrives in well-drained, sun-drenched soils.

Why Choose Prairie Onion?

• Late-summer color – Adds interest when many other natives are winding down.
• Supports pollinators – Excellent nectar source for bees and butterflies.
• Low-maintenance & hardy – Ideal for dry, rocky, or sandy soils.

Plant Prairie Onion in full sun and watch it flourish with minimal care, providing a burst of summer color and a valuable resource for pollinators!

• Drought-tolerant once established; water sparingly, only during prolonged dry periods.
• Deadhead flowers after blooming to maintain appearance and prevent self-seeding.
• Thrives in well-drained, sandy or rocky soils; avoid wet, poorly-drained soils.
• Divide clumps in the spring every 3-4 years to promote healthy growth and increase plantings.
• Requires minimal care once established. Monitor for pests but generally pest-resistant.
