Allium Collection


ALLIUM: Alliums are ornamental onion bulbs, planted in the fall planted. These stunning flowers draw a lot of attention with their 4-inch wide globes of tightly packed florets which sit at the top of a tall, thick, bare stem. The low strap-like foliage turns down as the plant blooms, making the spherical cluster of blooms a focal point in your garden.

The allium blooms are fragrant and bring a special addition to the garden. While often used for landscaping, these long stemmed flowers are ideal cut flowers. The blooms are pleasantly fragrant and this plant is an easy and prolific addition to the garden.

Best is to plant them in groups for an eye catching focal point. Alliums prefer to be dry during their dormancy. The Allium is ideal for mass plantings, borders, and cut flowers. These plants are rabbit, squirrel and deer resistant. They have a bloom period of about 3 weeks and they bloom in late spring to early summer.
