Appearing at the end of winter, Crocus blooms are a sign that spring is on the way and are an excellent pollen food source. They are easy to grow and like well drained soils that get a good amount of sunlight. If you are relaxed about your lawn care, Crocus can even be naturalized into yards for a splash of early spring color. Crocus come in a variety of colors and they bloom from fall to spring. If you are a fan of saffron, it is made from the dried stigmas of the fall blooming Crocus sativus. Unlike bulb flowers the Crocus corms gets completely absorbed into the flower and leaves during the bloom cycle and then will make new corms as the plant goes dormant again, so be careful not to destroy the plant during the growing cycle.
