Allium basalticum Silver Spring

A rare variety now grown professionally in the Netherlands, Silver Spring yields a gorgeous, 4”, composite flower that opens ivory with a pink glow and matures to bright white atop a 24” to 36” stem with low-growing, strappy foliage. It is rabbit-, rodent- and deer-resistant, and is adored by bees, butterflies and helpful pollinators. The flower looks like a fancy cupcake: its white-frosted bouffant dome is dotted with raspberry starbursts and little plum and apple-green sequins. This coveted variety has an exceptionally pleasant, honeyed fragrance, kind of like a sugary licorice bon-bon. A selection out of Allium nigrum, Silver Spring was discovered in 1999 by Dr. Rina Kamenetsky, Professor of Horticulture and Plant Physiology and an Allium specialist at Israel’s Volcani Center. Its pale green foliage begins to die back as, or before, the flower blooms. Bulb size: 10/12 cm. June/July. HZ: 4-7. Height: 24" to 36". We are very sorry, but due to state agricultural restrictions, we are not permitted to ship Allium bulbs to Idaho, or to the following five counties in the State of Washington: Adams, Benton, Franklin, Grant and Klickitat. Allium are The Art & Soul of Spring and Summer.

  • Information
  • Allium
    Latin for garlic, the Flowering Onions are available in diverse heights and sizes, are rabbit-, rodent- and deer-resistant, and are seldom affected by disease. Adored by bees, butterflies and pollinators, Allium extend the spring flowering season with bold, dramatic color and statuesque garden architecture. They are also valuable cut and dried flowers.

    Allium require full sunlight although there are several varieties that can also thrive in partial sunlight: A. cowanii, oreophilum and siculum bulgaricum. Allium require rich, well-draining and neutral pH soil and benefit from a summer dry period. A. unifolium can handle soil with a bit more moisture. All Allium must be planted outdoors in the fall after the soil has cooled down to around 55°F (normally after two weeks of night time temperatures hovering around 40°F). While most Allium are not recommended for forcing over the winter, there are several varieties that are known to be good forcers: A. cowanii, karataviense and unifolium. Please note that flower size is presented as the width, or diameter, from left to right.

    Plant the larger Allium bulbs 6" to 8" deep and 8" to 10" apart. Plant the smaller Allium bulbs 4" deep and 3" to 4" apart. Top size bulbs. Bloom time: May through August depending on the variety. Height: variable depending on the variety. Variable horticultural zones ranging from 3-10 depending on the variety.

    We’re very sorry, but due to state agricultural restrictions, we are not permitted to ship Allium bulbs to Idaho, or the following five counties in the State of Washington: Adams, Benton, Franklin, Grant and Klickitat.
