Small early-flowering crocus species with golden or cream flowers, often pushing through the last snow. Several weeks ahead of the larger spring crocus (C. vernus).

Growing notes
- Flowers a clear two to three weeks earlier than the larger garden crocus C. vernus already in the database — signals the very first stirring of spring
- Critical early pollen source for emerging queen bumblebees on warm winter days
- Naturalises freely in short grass — leave the foliage to die back before mowing
- Needs winter chilling to flower reliably
