Coreopsis gigantea (Giant Coreopsis) is a woody perennial plant native to California and Baja California. The stem is a trunk 1-2 m tall, 4-10 cm diameter. Bright green leaves and flowers are on the top of the trunk, the rest of the trunk is bare. The flowers are yellow, daisy-like, 6-20 cm. It is summer deciduous, leaving a bare trunk in summer.

Distribution [edit]
It is distributed on the South California central coast, north and central Southern California coast, the California Channel Islands, and further south on Guadalupe Island, Mexico. It is restricted to these frost-free areas because its stem is succulent. Storing water in this way makes the plants tolerant to drought but especially susceptible to frost.
Cultivation [edit]
The plant is very drought tolerant. It needs good drainage, is not tolerant of excess water, and should receive minimal water during summer.
