Allium tuberosum is
a perennial herb, reportedly uncertain if it is a native- or
indigenous species. Bulbs are small, connecting sideways in
a queue, and leaves are plane and linear, 20-30cm in length.
Flower stems grow to 30-50cm in height and set many white
flowers on the apexes. Perianth lobes measure 5-6mm in
length, in the shape of a narrow long-ovate, tips pointed.
Bloom time: August-September.
