Bulbocodium is a hardy bulb
Plants are very small in size reaching about 5 to 10 cm in height at most.
They therefore make great flowers for a rockery, where they flower in the early spring with yellow or purple crocus like flowers.
Common names for Bulbocodium include Spring Meadow Saffron and Hoop-Petticoat Daffodil.

If planning to grow Bulbocodium outdoors then bulbs should be planted at a depth of 7 cm (2 inches) in the autumn.
If you are attempting to grow them from seedm then they should be planted outdoors in the autumn on the soil surface.
