Wild tulips grow in cool, mountainous habitats that stretch from southeastern Europe to northern China.
Each plant has one long, smooth stem and two to twelve leaves.
The flower has three petals and three sepals that look just like petals. Six stamens hold pollen. The stigma, in the middle, becomes the seed pod.
Most tulips need a climate with a cold winter and a dry summer. Bulbs are planted outdoors in the fall. They need to spend up to 18 weeks at temperatures below 40°. This is called vernalization.
