Coreopsis gigantea, a perennial plant with woody stems and large, yellow flowers, native to California and Baja California

Coreopsis gigantea, also known as Giant Tickseed or Tree Coreopsis, is a perennial plant native to California and Baja California. Its unique appearance and striking yellow flowers make it a popular choice for gardens and landscapes.

One of the most distinctive features of this plant is its woody, trunk-like stems, which can grow up to 6-8 feet tall. These stems are often bare, except for the persistent leaf scars, giving the plant a sculptural quality. The leaves, which are clustered at the tops of the stems, are finely dissected and have a feathery appearance. They are typically bright green but may turn brown during the dry season.

The flowers of Coreopsis gigantea are large, daisy-like blooms with bright yellow petals. They are typically 3 inches in diameter and are borne on long, leafless stalks. The flowers bloom in spring and early summer and can attract pollinators like bees and butterflies.

This plant is well-suited for drought-tolerant gardens and landscapes. It prefers full sun and well-drained soil. While it can tolerate occasional irrigation, it is generally quite drought-tolerant. Coreopsis gigantea is a relatively low-maintenance plant and does not require frequent pruning or fertilization.

In addition to its ornamental value, Coreopsis gigantea also has ecological benefits. It provides food and habitat for native wildlife, including bees, butterflies, and birds. It is also a good choice for erosion control on slopes and embankments.
