Stresa is one of the true classics of the tulip world. It was one of the earliest hybrids from the mostly crocus-sized 'wild tulips,' and one that had two important rare characteristics: It was naturally a bi-color, and the flowers were large. The hybridizers quickly 'improved' it a bit, giving us a beauty that is still one of the most popular 'rockgarden' tulips in the world. Stems are only 10 to 12', but the blooms are large and retain their long, elegant shape and beautiful coloring. Best of all, Stresa, like other species or near-species tulips is dependably perennial. In many areas, it actually spreads.
