Tulips are spring-blooming perennials that grow from bulbs. Depending on the species, tulip plants can be between 4 inches (10 cm) and 28 inches (71 cm) high. The tulip's flowers usually bloom on scapes with leaves in a rosette at ground level and a single flowering stalk arising from amongst the leaves.
Tulips are an elegant blossom, long valued for their beauty and grace. Tulips have a place in the garden and in cut flower bouquets, or they may be planted in indoor pots to bring color to your home. Tulips are grown from bulbs and may blossom year after year in your flowerbeds, depending upon your climate.ome gardeners opt to re-use their bulbs each year, while others simply discard the old bulbs and start over with new ones each year. If you do want to reuse your tulip bulbs from year to year, cut the flower short approximately three weeks after blooming.
