Summer Beauty Ornamental Onion

About this plant

Allium tanguticum 'Summer Beauty' is a horticultural gem, celebrated for its robust nature and effortless elegance. From early summer through fall, this captivating perennial produces abundant globes of starry, lavender-pink flowers, creating a soft, airy effect in your garden. Unlike many other alliums, 'Summer Beauty' boasts attractive, grass-like foliage that remains lush and green throughout the growing season, even after the flowers fade. This makes it an exceptional choice for borders, rock gardens, or mass plantings where consistent beauty is desired. Highly adaptable and low-maintenance, 'Summer Beauty' thrives in a variety of conditions, resisting pests and diseases with ease. Its long-lasting blooms are perfect for cutting, bringing a touch of whimsical charm to your indoor arrangements.

Installation timing

When we're in season, outside of the winter months, our goal is to get your plants installed within about two weeks. That window gives us enough time to secure your plants from our supplier and find a spot on the schedule. Throughout the process we stay in touch through notifications and your existing client portal on the main A Cut Above website, which is separate from this landscaping plants shop.

Care & maintenance

Easily grown in average, well-drained soil. Drought tolerant once established. Deadhead spent flowers to encourage continuous blooming, though it will rebloom without intervention. Divide clumps every 3-4 years in spring or fall to maintain vigor.

Watering suggestions

Proper watering is the single most important factor in your plant's survival after installation. Newly installed plants have a limited root system and rely on you for consistent moisture while they establish.

• First 2 weeks: Water deeply every day (or every other day in cooler, wet weather), soaking the root ball and surrounding soil.
• Weeks 3–12: Water deeply 2–3 times per week, adjusting for rain, heat, and soil drainage.
• After establishment: Water deeply about once a week during the growing season, and more often in extreme heat or drought.
• How to check: Stick a finger 2–3 inches into the soil near the roots — if it's dry, it's time to water. Deep, less-frequent watering encourages strong roots; shallow daily sprinkles do not.
• Avoid: Overwatering (soggy, waterlogged soil) is just as harmful as underwatering and can drown roots.

Watering needs vary by plant, season, soil, and exposure. Because proper watering is the customer's responsibility after installation, please make sure you understand and can follow these suggestions before ordering.

Good to know: plants and trees purchased from and installed by A Cut Above include a one-year limited warranty from the date of installation. Because plant survival depends heavily on proper watering and care after installation, losses caused by improper care, neglect, animal or chemical damage, or extreme weather are not covered, and we must be given the chance to inspect a struggling plant before it's removed or replaced. Coverage is one replacement per plant. Read our warranty info.
