Crocus
Edible
Overview
One of the earliest signs of spring, crocuses push their jewel-toned flowers through the last of the snow, bringing hope and color to winter-weary gardens. These small but mighty bulbs naturalize and multiply over the years, creating ever-expanding drifts of purple, yellow, white, and striped blooms. They are essential early-season food for emerging bees and other pollinators.

Planting Calendar
When to sow, transplant, and harvest by growing zone.
| Zone | Action | Months | Notes |
|---|---|---|---|
| Cold (1-2) | Transplant | Sep — Oct | Plant corms in fall 3-4" deep; among the earliest spring flowers |
| Cold (1-2) | Bloom | Mar — Apr | Very early spring; may push through snow; critical early bee food |
| Cool (3-4) | Transplant | Sep — Oct | Plant in fall; naturalizes in lawns; plant 50+ for best effect |
| Cool (3-4) | Bloom | Feb — Mar | Late winter/early spring; first major pollen source for emerging bees |
| Moderate (5-7) | Transplant | Oct — Nov | Plant in fall; snow crocus (C. chrysanthus) blooms even earlier |
| Moderate (5-7) | Bloom | Feb — Mar | Late winter bloom; C. sativus (saffron) blooms in fall instead |
| Warm (8-9) | Transplant | Nov — Dec | Pre-chill corms 6-8 weeks; grows as annual in zone 9+ |
| Warm (8-9) | Bloom | Jan — Feb | Late winter bloom; may not rebloom reliably in warm zones |
