Crocus
Common Name: Crocus
Botanical Name: Crocus spp. (KRO-kus)
Decorative Life: Varies greatly by cultivar and temperature and to a lesser degree by light levels. Individual flowers last from 2-5 days but the entire plant longevity can be as high as 7-12 days if sold at the sprout stage of development and held in a cool environment.
Post Harvest Care:
  • Display in cool area for maximum life.
Harvest Instructions: Harvest and market at the sprout stage of development.
Family Roots:
  • Is a member of the Iridaceae (iris family).
  • Native from the Mediterranean region to South West Asia.
  • Common relatives include iris, ixia, freesia and gladiolus.
Personality:
  • Produced from corms, not bulbs. Corms are modified stems.
  • Classed as a monocotyledon, leaves mostly parallel veined.
  • Flowers are tubular, flaring to cup-shaped at ends, up to 3 inches long.
  • No fragrance of consequence.
Availability: Winter - spring.
Flower Color: Yellow, blue and/or white, often stripped.
Storage Specifics: 34-38F.
Tidbits:
  • "Crocus": Greek name of the saffron (C. sativus).
  • Can purchase corms, plant them, follow growing instructions and allow them to produce flowers thus extending the enjoyment period.
  • The American Academy of Allergy, Asthma and Immunology lists this species as an allergy-safe pollen producing plant.
  • Will generally do well in light levels at least bright enough to read a newspaper in comfort up to full sun.
Recent Findings: While the following is not a recent research finding to say the least, it still is very applicable today. Pfeffer (1897 as reported by Wood, 1953) showed that when light causes a less than one degree F increase in crocus temperature that flower opening can be stimulated whereas an equal fall in temperature can cause the flower to close.
