Crocus vernus - Dutch crocus

Nothing heralds spring more than the exuberant blooms of Crocus vernus, better known as Dutch crocus. Typically growing about 4 inches tall, this spring bloomer is actually a corm, not a bulb. A corm is a solid food-storing underground stem, while a bulb has fleshy leaves around the stem. Crocus open in the sunlight, closing their petals at night. If cool enough, the plants should bloom for 2-3 weeks. After that, let the leaves develop to store food for the next bloom time. The plant will go dormant after the leaves turn yellow and die back.
