Island Plant Adaptations Guide Stop 8

Examine closely the thick, brown stalks of giant coreopsis. Giant coreopsis has adapted to the dry conditions of the coastal bluffs by remaining dormant throughout the dry season; during these months the branches appear brittle and lifeless. However, in the spring, after rain has moistened the soil, giant coreopsis explodes with green foliage and bright yellow flowers. The flowers may last several weeks, depending on the amount of rain that has fallen. After it blooms and disperses seeds, giant coreopsis returns to dormancy in anticipation of the summer drought.
