Triumphs make up the largest grouping of tulip varieties and come in a wide range of vibrant colours. They are the result of crossing early and late single tulips, and, as a group, they tend to flower in mid to late spring. Their blooms retain the classic cup shape of their single tulip parents. While they are gorgeous flowers in any setting, triumphs tulips put on a spectacular show when planted in drifts, especially when several bright colours are grown together. Their attractiveness and long, strong stems work together to make them good cut flowers. Not all tulips force well indoors, but triumphs are an exception. Begin the forcing process in late summer or early fall to enjoy them during winter.
