Coreopsis gigantea with the common name giant coreopsis, is a woody perennial plant native to coastal regions of central and southern California and also to northern Baja California.[2][4][5]

Distribution[edit]

The plant is found in habitats on the California coastal sage and chaparral, from 45–180 feet (14–55 m) in elevation.[2][6] It is also found growing in coastal dunes, chaparral hillsides, and exposed sea bluff habitats.[6]

Coreopsis gigantea is distributed on the coasts of: Southern California and the Channel Islands; the Central Coast region; San Francisco Bay Area; and in Mexico on the northwestern Baja California Peninsula and Guadalupe Island.[2]

It is restricted to nearly frost-free habitats because its stem is succulent, being tolerant to a cold temperature of around 25 degrees F.[7] Storing water in this way makes the plants tolerant to drought but especially susceptible to frost.

Description[edit]

The stem of Coreopsis gigantea is a trunk measuring up to 1 metre (3.3 ft) tall, and 4–10 centimetres (1.6–3.9 in) in diameter. The plant can reach 4 feet (1.2 m) in height by 2 feet (0.61 m)in width.[6] It is summer deciduous, leaving a sculptural bare trunk and branches during the dry season.

Flowers with bright green leaves grow on the top of the trunk, while the rest of the trunk is bare.

Coreopsis gigantean flowers are yellow, daisy-like, 6–20 cm in diameter and they bloom in the spring and early summer.[6]

Cultivation[edit]

Giant Coreopsis is cultivated as an ornamental plant by specialized nurseries.[6][7] It is planted in native plant, drought tolerant, and wildlife gardens, and in natural landscaping and habitat restoration projects.[7]

The plant though drought tolerant, needs good drainage and is not tolerant to excess moisture, and needs minimal watering during the summer.[7][8]
