Global_description

Allium neapolitanum is a perennial bulbous herbaceous plant. The bulbs vary in size from 1 to 2.5 cm in diameter; numerous bulblets are usually present. The leaves are linear to narrowly lanceolate, glaucous, emerging out of the ground in clusters of 2 to 6. The inflorescence is a loose umbel at the tip of a stalk (scape) 20-70 cm tall. Two whitish triangular bracts 1-3 cm long subtend the umbel. The white flowers of 3 sepals and 3 petals are arranged in clusters of 2-6 at the tip of rays 1-7 cm long. The fruits are small obovoid capsules.
