On Tuesday, the field school explored near the edge of Sibiloi National Park to learn more about adaptive strategies of vegetation in such an arid environment. In particular, we focused on the desert rose, Adenium obesum, a rather amazing tree. The desert rose is an incredibly slow growing tree, growing an average of 1 millimeter per year. It has a very thick trunk for water storage, a waxy coating to help retain water in such an arid environment, and produces rather few leaves and flowers per year to conserve energy. But when it does produce flowers, they are a brilliant pink, and radiate against the harsh landscape.
