Call them wild, species or botanical, but don’t let the name stop you from trying this type of tulip in your garden. Unlike the hybrids that can peter out in their second year of bloom, the species tulips grow wild in tough conditions: mountain ranges and gorges. Planted in favorable settings in a garden, they will blossom year after year, putting on a colorful show. While the flowers and plants may be smaller than the hybrid varieties, the colors are just as vibrant. The species varieties generally are hardy to Zone 3 and range from 4 to 10 inches in height. The swatch of colors is impressive (click here to see a few), from reds to yellows to pinks to duo-tones.
