Saffron Crocus (Crocus sativus) blooms in autumn with lovely lilac petals enclosing three deep orange-red stigmas per flower. These are the source of what we know of as saffron, the world’s most expensive spice. Not only are these lovely crocuses a source of visual candy in the fall, but you can harvest the spice yourself and enjoy them in recipes throughout the year. Plant your saffron Crocus bulbs as soon as they arrive in late summer. They will sprout and grow in about 6-10 weeks (sometimes in as little as 4-6 weeks), putting on a colorful fall display. If there is danger of frost in your area, plant in containers that can be brought indoors.

USDA Hardiness Planting Zones
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.
- If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
- If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
