Allium neapolitanum (Ornamental Onion)

White Allium, Allium Cowanii, Naples Garlic, Ornamental Garlic, Bride's onion, Daffodil Garlic, Spring Bulbs, Spring Flowers


Allium neapolitanum (Naples Garlic) is a beautiful, profusely-flowering ornamental onion with sweetly-scented clusters of white, star-shaped flowers forming umbels up to 3-4 in. wide (7-10 cm), atop narrow, green leaves. Blooming in late spring to early summer, this spectacular Allium enjoys long-lasting blooms and remains ornamental in the garden well into summer. Excellent cut flowers.

  • Growing up to 10 - 12 in. high (25 - 30 cm), this beauty naturalizes easily and will come back year after year!
  • Easily grown in rich, sandy to gritty, dry to medium moisture, well-drained soils in full sun. Drought tolerant.
  • Attracts butterflies, but deer ignore it!
  • Stunning in beds, borders, rock gardens, cottage gardens or as ground cover. For best visual impact, plant in groups (at least 20 bulbs).
  • Fragrant, it mixes beautifully with perennials and creates stunning combinations with pink Geraniums or purple Irises.
  • To be planted in fall.

Many hundreds of Allium species exist, but only a modest few have made a name for themselves as garden plants. The ornamental onions distinguish themselves by their great 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. All species can be used in the border. Certain small species are just perfect for a rock garden, and several lend themselves to naturalizing.
