Its blooms reopen each morning larger and brighter than they were when they closed the previous evening. The bell-shaped, 4" flowers emerge with sunny yellow petals with rich rose-red edges and flames, which grow darker as the blooms age. Triumph Tulips are the result of crossing between long stemmed Darwin Tulips and varieties of the short stemmed Early Tulips. When planted outdoors, their flowering time is in-between these varieties, blooming late April/early May. With their strong stems, large flowers, and medium heights, Triumph Tulips are excellent as pot plants for Valentine's Day and Easter. Also superb in beds or borders.
