Bulbs and bulblike plants, Perennials
Tulips vary considerably. Some are stately and formal, others dainty and whimsical; a few look decidedly bizarre. Bloom comes at some time from March to May, depending on the type.
Use larger tulips in colonies or masses, in company with low, spring-blooming plants. Use smaller, shorter types for close-up viewing—in rock gardens, near paths, in raised beds, or in patio insets.
Tulips are superb container plants; unusual kinds such as Rembrandt and Parrot are especially suited to this use.
Nearly all hybrid tulips and most species (wild) tulips need six weeks of temperatures below 45°F/7°C to initiate flower formation, and they aren’t bothered by summer drought. In mild climates, provide the necessary chill by refrigerating bulbs for 6 weeks (not near ripening fruit) before planting; then treat the plants as annuals.Tulipa bakeri
