Allium 'Summer Beauty' is a bulbous perennial with charming, rounded umbels, 2 in. across (5 cm), packed with up to 30 soft lavender-pink, bell-shaped flowers. Blooming in mid-to-late summer, the luminous flowers are borne on sturdy, upright stems above the foliage of onion-scented, strap-shaped leaves, which remain attractive all season long. The flowers are both long-lasting and excellent as cut flowers.

  • Recipient of the Gold Medal Award of the Pennsylvania Horticultural Society.
  • Grows up to 12-18 in. tall (30-45 cm) and 18-24 in. wide (45-60 cm).
  • Thrives in fertile, well-drained soils in full sun to part shade. Add grit to clay soils to improve drainage. This Allium is drought tolerant.
  • Lovely in beds and borders, cottage gardens, and containers. To achieve an impressive visual effect, plant in clusters of at least three to five close together.
  • Known for attracting bees, butterflies, ​moths, and other pollinators, but deer ignore it.
  • Generally pest and disease free.
  • Cut back after flowering or merely remove dead flowerheads.
  • Propagate by seed, or division at any time.

Hundreds of Allium species exist, but only a few have made a name for themselves as garden plants. The ornamental onions distinguish themselves by their remarkable diversity in color, inflorescence, and flowering height. Many species bloom in early summer - just after the spring-flowering period and just before the exuberant full bloom of summer. Certain small species are just perfect for a rock garden, and several lend themselves to naturalizing. All species can be used in the border.
