Alliums White


The Allium ‘Nigrum’, a fall planted ornamental onion bulb, will produce white flowers. This flower is sure to turn heads with its 4-inch wide globes of tightly packed white florets which sit at the top of a tall, thick, bare stem. Alliums prefer to be dry during their dormancy. These plants are rabbit, squirrel and deer resistant. The Nigrum has a bloom period of about 3 weeks and they bloom in late spring to early summer.
