While some gardeners mark the vernal equinox on their calendar as a sort of unofficial start to the flower gardening season, those who plant their favorite crocus varieties may be rewarded a two full months earlier than that. Short on stature but big on charm, crocus flowers require little more than an undisturbed space in the landscape where they can gradually multiply into handsome colonies.
The Crocus genus comprises at least 90 species that grow from bulb-like corms. Of these, a relatively small group is commonly cultivated for garden use, including some that are spring bloomers: C. tommasinianus (snow crocus), C. vernus (Dutch crocus), and C. chrysanthus (golden crocus or snow crocus). There are also some fall-blooming crocus species, including C. sativus (saffron crocus).
Crocuses have been in cultivation since the 1500s, and there are hundreds of varieties available — consider these 14 crocus varieties for your garden.

Snow Crocus (Crocus Tommasinianus)

Gardeners have been enjoying this pale lavender heirloom since 1847. In the early morning light, snow crocus petals appear almost silvery, giving the flowers a luminous effect. Also known affectionately as "Tommies," Crocus tommasinianus is resistant to squirrels. The flowers open in the morning and close up at night, but, on cloudy, rainy days, they don't open at all. It's called snow crocus because it's among the first crocuses to open in spring.

Crocus flowers fare best in lawns that don't receive heavy summer irrigation, as they prefer to be on the dry side during dormancy. This is another Dutch crocus (C. vernus), which generally flowers slightly after the early snow crocuses.

The purple 'Grand Maitre,' a giant crocus, blooms a bit later than many other species, allowing you to stagger and extend bloom times. On sunny days, the petals open very wide, revealing the contrasting orange stamens within. 'Grand Maitre' corms will multiply in lawns if you leave the foliage until it withers, which usually happens about six weeks after flowering.

This is a cultivar of C. chrysanthus, another of those sometimes called snow crocuses. It's also sometimes called "golden crocus," since many varieties are golden yellow. 'Skyline' blooms very early, before the Dutch crocuses.

About 25 bulbs will yield enough saffron threads for one household.
