Which spice is obtained from the plant Crocus sativus
Crocus sativus Depending on the size of harvested stigmas, 50,000–75,000 "Crocus sativus" plants are needed to produce about 1 pound of saffron; each flower only produces three stigmas. Stigmas should be harvested mid-morning when the flowers are fully opened. The saffron crocus ("Crocus sativus") should not be confused with "meadow" saffron or autumn crocus ("Colchicum autumnale") which is poisonous. Crocus sativus Crocus sativus, commonly known as saffron crocus, or autumn crocus, is a species of flowering plant of the "Crocus" genus in the Iridaceae family. It is best known for producing the spice saffron from the filaments that grow inside the flower.
Crocus sativus blooms with purple flowers in the autumn. The plant grows about 10 to 30 cm high. "C. sativus" is a triploid with 24 chromosomes, which means it has three times the haploid number of chromosomes. This makes the plant sterile due to its inability to pair chromosomes during meiosis. "Crocus sativus" is unknown in the wild, and its ancestor is unknown. The species "Crocus cartwrightianus" is the most probable ancestor, but "C. thomassi" and "C. pallasii" are still being considered as potential predecessors. Manual vegetative multiplication is necessary to produce offspring for this species as the plant itself is a
