Allium nigrum var. purpureum, Spring Bulbs, Spring Flowers
Allium atropurpureum is a hardy perennial bulb with star-shaped, deep purple-red flowers packed into a half-globe umbel, 2 in. wide (5 cm). Each flower consists of deep merlot-purple florets adorned with blueberry-purple eyes, which create a wonderful contrast of colors. Blooming in late spring to early summer, the flowers are borne on sturdy, upright stems above strap-shaped green leaves. If left in the garden after the flowers have faded, the seed heads will remain ornamental and add months of interest.
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.
