New Zealand Cabbage Tree Palm Seeds

Landscape Rating: ⭐⭐⭐⭐⭐ (5/5 Stars)

Plant Characteristics

Despite its common name, New Zealand Cabbage Tree is not a true palm but one of the most dramatic palm-like landscape plants available. Native to New Zealand, this evergreen tree develops a slender trunk topped with dense crowns of long, sword-shaped leaves that create an unmistakably tropical appearance.

Young plants typically begin as a single trunk, eventually branching into multiple heads as they mature. Established specimens often reach 20 to 40 feet in height and develop a striking architectural form that becomes increasingly attractive with age. The narrow green leaves sway gracefully in the wind, giving the tree movement and character throughout the year.

During late spring and early summer, mature plants produce enormous clusters of fragrant creamy-white flowers that can contain thousands of blooms. These are followed by small white berries that attract birds and other wildlife.

Landscape Uses

• Specimen lawn tree
• Tropical-style landscapes
• Palm substitute for cooler climates
• Coastal gardens
• Modern architectural landscapes
• Poolside plantings
• Mediterranean-style gardens
• Container specimens when young

Its bold silhouette makes it a natural focal point in lawns, entryways, courtyards, and mixed tropical plantings.
