In California, tulips are usually a one year proposition as they need colder temperature to rebloom. However, they are the very harbinger of spring and their vibrant and varied colors give a jolt of pleasure as they emerge after the dreariest of seasons. Darwin Hybrids are the one group that have the best chance of re-blooming if given no summer water.
Culture: Plant about 2-4 inches below the surface of the soil depending on whether they are to be left in the ground, and water well. I replace them every year, so I plant them shallowly to facilite pulling them out after bloom.
