Crocus

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.

ZoneActionMonthsNotes
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
