Flowers are the most preferred gifts for special occasions like a wedding, Mother’s Day and Valentine’s Day. A fleeting beauty that blooms as infrequently as once a year. And when it does bloom, it does so in the dark of night and withers away before dawn. Due to its rarity and beauty, the Gold of Kinabalu Orchid is one of the most expensive flowers ever sold. The Saffron Crocus is one of the most expensive flowers on the earth. The Eustoma grandiflorum, more commonly known as Lisianthus, is a flower that blooms annually.
