Only perennial tulips like Darwin Hybrid, Species, Greigii, Fosteriana, and Kafmanniana will return. These tulips are considered perennial bulbs in zones 3-8. They need cold to flower, so warmer climates may not see the return of tulips they purchased as starts in pots. Make sure to leave the leaves of the bulb intact. These leaves energize the bulb and ensure it recharges to bloom again the following year.
