| Coreopsis gigantea | |
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
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
The plant is very drought tolerant. It needs good drainage, is not tolerant of excess water, and should receive minimal water during summer.
