Crocus vernus is a hardy bulb or corm also known as the Spring Crocus and Giant Crocus (also Dutch Crocus). A number of varieties are available for sale, all with similar growing requirements.
The first two names give us a good idea about its habit. Flowering in spring and with a large flowers. The ‘Dutch’ part is a little more obscure as this relates to where it was hybridised rather than where it originally came from.
Originally from alpine areas from France and Italy through to Austria and Serbia Crocus vernus is at home in a cold winter (covered in snow) and a dry summer. In warmer areas protection from hot sun in summer is desirable.
Crocus vernus Care and Growing Conditions
Often used as a bulb to naturalise into lawns, Crocus vernus is at home in a woodland setting or planted in a clump beneath deciduous trees.
As these are spring flowering this is ideal as they get sun in late winter to spring (flowering time) and then protected from the drying summer sun.
These are easy care bulbs in USDA Zones 3 – 8.
Bulbs can be lifted and divided after foliage has died back if required.
