ARA) - Tulips are a vibrant, timeless symbol of spring. They are available from January through May and join groundhogs, green grass and new leaves on trees as indicators that warmer weather is on its way. Their delicate shape, graceful posture and vibrant colors have inspired this flower's popularity across cultures and throughout time.

With more than 100 species and 500 different varieties, tulips are one of the largest members of the lily family. They are most often found in shades of red, yellow, violet and white. Two-tone and variegated varieties of tulips are also becoming increasingly popular.

Tulips are unique in that they continue to grow after cutting. Their stems will often extend up to two inches after they are clipped. Also, the flowers' attraction to sources of light may cause tulip stems to bend, twist and turn into new and beautiful positions.

To maximize the vase life of your flowers, floral experts recommend that you select tulips with tight flower heads.

Cut off at least 1/2 inch of the flower stems before placing your tulips in a vase filled with cool water. It is not necessary to add flower foods or preservatives to cut tulips. With proper care and handling, your flowers should last between four and seven days.
