Bunching Onions (Allium fistulosum) are cultivated both for their culinary uses and their ornamental value. These small bulbous perennials feature attractive, ivory-white, globular to somewhat elongated flowers, atop hollow round stems and tube-like semi-evergreen leaves. Fast growing and very easy to grow, Bunching Onions are hardy, take up very little space and are excellent in oriental stir fries, soups or salads. Usually mild, their flavor tends to be spicier during the summer.

  • Blooming in late spring - early summer, Bunching Onions typically grow in clumps up to 24 in. tall (60 cm) and 12 in. wide (30 cm). They go dormant during the winter and will multiply by forming perennial evergreen clumps.
  • They thrive in light, fertile, nutrient-rich and well-drained soils in full sun to part shade. While drought tolerant, regular moisture is required for optimum growth.
  • Generally pest and disease free, they are deer resistant and make lovely additions to borders, herb gardens, vegetable gardens. Plant them in groups for best visual impact.
  • Bunching Onions can be grown from seeds and be harvested the first year. Once established, you may divide them (at almost any time of the year, though the spring is probably best) to make more plants.
  • The world of Bunching Onions offers very attractive cultivars which vary in size, vigor, leaf color, length and hardiness: 'Santa Clause' and 'Red Beard' with beautiful red skin, 'Shimonita' with thick and shorter stems and extremely cold-hardy varieties such as 'White Lisbon', 'Evergreen White Bunching' and 'Winter Over'.
