How to Identify
Crocus serotinus is a small corm reaching 0.1 m tall, hardy to UK zone 6 and not frost tender. Foliage appears November to May with flowers November to December. The plant is hermaphroditic, pollinated by bees and butterflies. Grows in light sandy to medium loamy soils with mildly acid to mildly alkaline pH. Tolerates semi-shade or full sun and adapts to dry or moist soil conditions.
How to Grow
Succeeds in most soils, conditions and positions. Plants grow well in a peaty soil in a bulb frame and should succeed outdoors in a sandy peaty soil. The subspecies C. serotinus austriacus can be naturalized in grass or beneath deep rooting trees on light well-drained soils. Plants tend to move considerably from their original planting place because of their means of vegetative reproduction, it is therefore wise not to grow different species in close proximity. Any planting out is best done in late spring or early summer. Mice are very fond of the corms of this species. Plants take 3 - 4 years to flower from seed. The flowers are only open during the day time, closing at night.
Propagation: Sow seed as soon as it is ripe in light sandy soil in pots in a cold frame, or alternatively in a cold frame in early spring. Seed usually germinates freely, so sow thinly; germination occurs within 1–6 months at 18°c. Avoid transplanting seedlings in their first year unless overcrowded, but apply regular liquid feeds to prevent nutrient deficiency. Once the plants die down, divide the small bulbs and plant 2–3 per 8cm pot. Grow on for a further two years in a greenhouse or frame, then plant out into permanent positions when dormant in late summer. Expect 3–4 years from seed to flowering. Clumps can also be divided after the leaves die down in spring, and bulbs planted directly into permanent positions.
Medicinal Uses
None known
Other Uses
A yellow dye obtained from the stigmas serves as a saffron substitute.
