How to Grow Crocus Sativus Linneaus

Crocus sativus linneaus is the flower that produces the expensive and coveted spice saffron. The crocus flowers have scarlet stigma at the center of the bloom that are harvested and dried to produce the coveted seasoning. The crocus prefers cold winters and hot summers and blooms in the fall. Grow saffron in U.S. Department of Agriculture zones 6 through 9. The bulbs can also be grown in pots in areas with less suitable climates. Divide the bulbs every three years for the best production.

Instructions

- 1
  Plant the saffron bulbs in fall when soils have warmed up enough to work them. Use a tiller to break up clods and aerate the soil to a depth of 10 to 12 inches. Incorporate 3 to 5 inches of compost at the same time. This will add nutrients, increase tilth and help conserve moisture.
- 2
  Use a rake to make a raised bed of at least 6 inches. It can be any length and width. The raised bed will ensure good drainage. This is essential so the bulbs don't rot. Make holes 6 inches apart that are 3 inches deep.

  Set the bulbs in the holes with the pointed side up to the sky. Fill in the holes and compress the soil. Water them weekly unless your zone receives at least 1.5 inches per week. If your zone receives the required amount of water you will not need to give supplemental irrigation.

  Fertilize in spring with a good bulb fertilizer following the amount recommended by the manufacturer.

  Harvest the stigma in mid to late fall when the flowers are almost spent. Cut them out carefully with scissors. Bring the stigma indoors to a warm room and place them on paper towels to dry for three to five days. You can also use them fresh.
