Bold, cup-shaped blooms in nearly every color imaginable make the tulip one of spring's most anticipated and rewarding garden moments.
Tulipa gesneriana, the garden tulip, is the parent species behind the thousands of cultivated tulip varieties we know today. Originally native to central Asia and the mountainous regions of Turkey and Iran, tulips were brought to Europe in the 16th century and triggered one of history's most famous economic manias - Tulip Mania - in the Dutch Golden Age. Their cultural legacy is matched only by their visual impact in the spring landscape.
Modern garden tulips are grouped into 15 official divisions, from the elegant Single Early types to the fringed Parrot tulips and the multi-petaled Double Late varieties. They range in height from compact rockery forms to stately 28-inch border giants. Whether planted in sweeping drifts or formal rows, tulips deliver a reliable, luminous burst of color when most other plants are just waking up.
Plant bulbs in autumn, 6-8 weeks before the ground freezes, at a depth of roughly 3 times the bulb's diameter - usually 6-8 inches deep. Choose a spot with full sun and well-drained soil; tulip bulbs will rot in soggy conditions. Space bulbs 4-6 inches apart and place the pointed end upward. In warmer climates (Zones 7-8), refrigerate bulbs for 6-8 weeks before planting to simulate the cold period they need.
Water after planting to settle the soil, then let winter rains do the work. In spring, water regularly if rainfall is scarce. After blooms fade, deadhead the spent flowers but leave the foliage in place until it yellows naturally - this allows the bulb to store energy for next year. In many climates, tulips perform best when treated as annuals and replanted each fall, as performance declines after the first year without a distinct cold-warm cycle.
In Zones 3-6 with reliable cold winters, tulip bulbs can often stay in the ground year-round and return for several seasons. In warmer zones or heavy clay soils, dig bulbs after foliage dies back, let them cure in a warm dry spot for a week, then store in a cool, dry, ventilated bag until fall planting. Squirrels love tulip bulbs - planting with a layer of wire mesh just above the bulbs is a simple, effective deterrent.
Tulip grows best in full sun.
Give it about 0.5-1 in per week during active growth; minimal when dormant.
Tulip is usually ready in blooms mid-spring, typically 14-28 days after emergence depending on variety.
