Where to Plant Crocuses
Crocuses do best in a spot that gets full sun (6+ hours of direct sunlight), but will grow in partial sun as well. Choose a planting site where there is well-draining soil; the corms will rot in soggy, compacted ground. Before planting, work in organic matter such as compost to a depth of at least 10 inches.
When to Plant Crocuses
- Crocuses need to experience an extended period of cold weather in order to bloom, so plant them in the fall to get spring blooms.
- Before the ground freezes in the fall, crocus corms can be planted most anywhere, except in the dense shade on the north side of buildings or under thickets.
- Ideally, plant crocus corms 6 to 8 weeks before a hard frost is expected in the fall and when the soil temperature is below 60°F (16°C). This is usually during September or October in the northern U.S. and Canada, and October or November in the southern United States.
How to Plant Crocuses
- Plant crocus corms 3 to 4 inches deep (with the pointy end up). After planting, water well.
- Plant bulbs in groups or clusters rather than spacing them in a single line along a walkway or border. Single flowers get lost in the landscape. Plant a few inches apart, and plant in groups of 10 or more.
- Consider planting crocuses in lawns and meadows where they can form carpets, or mass them in the front of flower beds along the edge.
- Plant taller spring-flowering bulbs and shrubs behind the early bulbs for color contrast.

You purchased (what is in all likelihood) a forced bulb. Growers have ways of hastening plant/bulb maturity on a schedule that is slightly different from that of mother nature because we love to see blooms in the spring! Most forced bulbs can be planted and naturalized into an environment. See above (or below in another question) for guidance on what to do with it after the bloom fades, as you wait for the cold weather of early winter to plant it.
Hi Moe,
You planted the crocuses with plenty of space. There's no need to change a thing!
At that location, you are just outside of the recommended planting range for Crocus (see the USDA Planting Zones), but it may be worthwhile trying a few bulbs in a cool spot on your property anyway. Typically, though, Florida does not get cold enough for long enough for the bulbs to have an appropriate cooling period. We would recommend contacting your local Cooperative Extension Service, which will be able to give you localized gardening advice.
You can grow crocus sativus and harvest the culinary saffron in minute amounts. Dutch saffron refers to a company that sells these bulbs from Holland. Vendors ship in the fall and the bulbs should be planted on receipt. Search around for vendors and be sure that the plants will survive in your planting zone.
