They are one of the first flowers to bloom in the spring, often appearing even when there is still snow on the ground, much to the delight of Colorado gardeners! The ability of crocus to bloom even through a layer of snow makes them a symbol of resilience and signals the arrival of spring.
Interestingly, crocuses are often used as a source of saffron, a spice that is derived from the dried stigmas of the crocus flower. But don't attempt to harvest saffron from their stigmas for cooking because crocuses are toxic if ingested (and care should also be taken if planting them in areas where pets or livestock may graze).
Winter weary bees are attracted to crocus' bright colors and sweet honey-like scent.
You can plant crocus in two seasons
Plant the corms September–November for an early spring display. You can also plant autumn-flowering crocuses and in late summer for autumn and early winter color.
The word "crocus" is derived from the Greek word krokos, which means "saffron".
