Propagate by division or separation - Plant the bulbs 5" beneath the soil surface in the fall. After the leaves have died back following flowering, dig up the bulbs and allow them to mature in a warm, dry location. In the fall, replant large bulbs, and place the smaller bulbs in a starting bed to mature. When enlarged, plant them in the garden.

Remove faded flowers, and do not remove the foliage until it has yellowed and begun to die back (up to 6 weeks).
These tulips do not perform well in Zones 7 to 9. To grow in these Zones, purchase cold-treated bulbs and grow as annuals. A few cultivars are suited to perennial warmer growth.
