About Winter crocus
Crocus imperati, also known as Imperato's Crocus, is a small perennial bulbous plant that blooms in late winter and early spring. Its delicate flowers, often purple on the outside and violet or white on the inside, open with the sun and close at dusk. It is ideal for rock gardens, path edges, or for naturalizing in lawns, providing an early splash of color.
Native range
Italy (Campania region)
Care tips
It requires full sun or light partial shade for optimal flowering. It prefers well-drained, sandy, or gritty soils; avoid waterlogging, especially during its summer dormancy. Water moderately during growth and flowering, drastically reducing once the leaves begin to yellow. A common mistake is planting it in heavy, poorly drained soils, which can lead to bulb rot.
How to save a dying Winter crocus
- Warning signs
- Yellow or soft leaves, flowers that don't open or wilt quickly, soft or moldy bulb.
- First aid
- Check the bulb: if soft or foul-smelling, discard. If firm, replant in well-draining substrate, avoid overwatering.
- What kills it
- Overwatering is fatal; it rots the bulb. Also lack of winter chill or poor drainage.
- Can it be saved?
- Yes, if the bulb is not completely rotted. Act quickly at the first sign of rot.
