Crocus
Crocus spp.
Family Iridaceae
Purple, gold, and white confetti scattered across a half-frozen lawn — crocus blooms before winter has officially surrendered, and a hundred bulbs cost less than one shrub. The tommies — Crocus tommasinianus — are the insider pick: the type squirrels reliably skip.
For honeybees staggering out on the first warm afternoon, crocus is the only breakfast in town — the earliest forage the year offers. It tucks into lawns, path edges, and pots, finished before mowing season. Plant a generous handful this fall; February gratitude is real.

What each band means

These are the species' typical months — expect them a few weeks earlier in warm zones and later in cold ones. Watch the plant, not just the calendar.
