What is the structural adaptation of tulips?

Tulips in the wild grow in a variety of habitats in western Asia, from moist valleys to arid mountain slopes. In general, the summers are dry and even the valleys lose much of their moisture. You'll find tulips growing in grassy meadows, separate rather than in large clumps. Their evolution has prepared them to survive well in these open, exposed habitats with cold, moist winters and warm, dry summers. As species develop, their features change as the individuals that produce more offspring influence the gene pool as a whole. For instance, the waxy, somewhat stiff petals of tulips are good protection from cold, drying winds for the stamens and pistils. It is likely that the tulips with more vulnerable petals lost their flowers to late frosts or a desiccating wind. The waxy-petaled flowers ripened more seed and became the parents of a new generation of tulips with tougher blooms.
