Nursery contributed plant descriptions

Allium 'Mont Blanc' has large, fragrant, white spheres the size of baseballs on 3-4 foot stems. Few plants can offer the unique flower forms of ornamental onions. Every garden should have Alliums. Plant in multiples of 3, 5, 7 or more. Don't fret when foliage starts to die back just before flowering. It's normal. Just trim the leaves.
Impressive, 5 to 6 in. creamy white spheres perch atop brawny, straight, green glistening stems, evoking a snowy mountain's majestic appeal. The tallest of the white flowering Alliums, this long blooming luminous beauty can be superimposed en masse against a dark backdrop or interplanted amid quantities of purple flowering Alliums. Coveted by gardeners, florists and bees, vigorous 'Mont Blanc' yields long strapping leaves persisting 'til flowering time and is distasteful to those fretful deer.
