Ornamental Onion 'Mont Blanc', Spring Bulbs, Spring Flowers
Tall and white, as suggested by its name, Allium ‘Mont Blanc’ is a splendid beauty with 4-inch wide (10 cm) umbels of pure-white flowers atop sturdy, upright stems. The foliage of basal, semi-erect strap-shaped grayish-green leaves is also quite ornamental. Blooming in late spring to early summer, this spectacular bulbous perennial enjoys long-lasting blooms and remains ornamental in the garden well into summer.
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.
