The term “cordyline” comes from the Greek word “kordyle,” meaning “club,” and refers to the woody stems that characterize these plants.

Taxonomic Information

Appearance

Cordyline plants can vary in size from small shrubs to tall trees, depending on the species. They typically have a single stem, which may be branched or unbranched, and long, narrow leaves that can be up to three feet long. The leaves are arranged in a spiral pattern around the stem and have a leathery texture. The flowers of cordyline plants are small and inconspicuous, and they are usually followed by small berries.

Care Guide

Cordyline plants are relatively easy to care for and can thrive in a range of conditions. Here are some tips for keeping your cordyline plant healthy:

• Water: Cordyline plants prefer moist but well-draining soil. Water them regularly, but be careful not to overwater, as this can lead to root rot.
• Fertilization: Feed your cordyline plant with a balanced fertilizer every six months to promote healthy growth.
• Soil: Cordyline plants prefer slightly acidic soil that is rich in organic matter.
• Sunlight: Cordyline plants thrive in bright, indirect sunlight. Avoid placing them in direct sunlight, as this can scorch their leaves.
