The flowers of Allium bulgaricum otherwise known as Nectaroscordum siculum are bell-shaped and grow in loose umbels. The stalks of the flower cluster all arise from one point like spokes of an umbrella. The color is unusual; green and purple with white edges. The bulbs are easy to grow and bloom in May and June. Deer do not bother the plants.

Cousins to onions, alliums often carry the family name and live up to it. Rosenbach onions, Allium Rosenbachianum, release a pungent aroma when cut. Deep violet blooms measure 5 inches across and grow on 2-foot leafless stems. The flowers, somewhere between rose and purple hold their form and color for three to four weeks and are excellent for both cut and dried bouquets. Allium Rosenbachianum is grown for its flowers.
