Bellevalia dubia is a perennial onion plant that reaches heights of 15 to 40 centimeters. The leaves are 4 to 13 millimeters wide and prostrate.

The flowers are 5 to 10 millimeters in size and cylindrical-bell-shaped. They are initially sky-blue in color, later they turn gray-violet or brownish with green-veined, white tips.

The capsules have wide, obverse-shaped, 7 to 10 millimeters wide flaps that are edged at the tip.

The flowering period extends from March to April.
