Crocus sativus is a perennial plant, up to 6 inches (15 cm) tall. Each corm produces several upright, cup-like, lilac-purple flowers with dark purple veins that bloom in early to mid-autumn. Each flower has three long style branches tipped with reddish-orange stigmas. Flowers close at night and open up in the morning. Basal, grass-like leaves appear slightly prior to bloom.

How to Grow and Care

In areas where Saffron Crocus are reliably hardy—USDA Zone 6 through 8 in the South, 6 through 9 in the West—you should plant the corms as soon as you receive them. Saffron Crocus do best in full sun and well-drained soil that is moderately rich in organic matter. Ideally, the site should be relatively dry in summer, when the corms are dormant.

Plant the corms 4 inches (10 cm) deep and 4 inches (10 cm) apart. If gophers, mice, or voles are a problem in your garden, plant the corms in containers or line the bed with hardware cloth or a similar wire mesh. Flowers generally come up 6-8 weeks after planting, although occasionally they wait until the 2nd fall to appear. Bloom lasts about 3 weeks. The grass-like leaves may emerge either with the flowers or soon after they appear. Sometimes they wait until the following spring. In either case, the leaves persist for 8-12 weeks, then wither and vanish, leaving no trace of the corms below until the flowers appear again in fall. It’s not a bad idea to mark the area where you’ve planted your corms, so you don’t inadvertently dig them up while planting something else… – See more at: Growing and Harvesting Saffron Crocus.
