Native to Asia Minor and central and southwest Asia, drumstick alliums have been cultivated since the early 20th century. Adding height and drama to the sunny border and to floral arrangements, 'Firmament' produces enormous, long-lasting, ball-like heads of small, star-shaped, vivid-purple flowers with shiny, silvery anthers in late spring or early summer. Profile
did you know?Ornamental onions are cousins to such edibles as onions, garlic, chives, and shallots, though few give off any significant onion odor to detract from their beauty. The pungent aroma characteristic of the genus is usually obvious only if you tear a leaf. Martha uses these bold, dramatic plants throughout her flower beds as punctuation points. general maintenance:To encourage the plants to store nutrients for next year's bloom rather than produce seeds, deadhead spent flower heads. how to sow/plant:Plant in fall, about 6 weeks before the ground freezes. Set bulbs 4?6 inches deep and 4?6 inches apart. There is no need to water or fertilize after planting. water and fertilize:Monitor soil moisture all season. If desired, feed with an all-purpose bulb fertilizer when shoots emerge in spring and again after bloom. garden hint:Ornamental onions are good news for gardeners who have lost other plants to animals; because of their taste, they are usually left alone by rabbits and deer. features:
