Yellow-flowered crocuses and smaller sized crocuses belong to other species; all have ephemeral flowers which last about a day before drying & withering; utilized in rock gardens, beds, base of trees, and in lawns; in lawns, foliage must remained intact for about 6 weeks, not mowed down, as leaves generating food for next year's floral production; flowers remain closed in full shade..
