Carpentaria acuminata: Carpentaria Palm1

Edward F. Gilman and Dennis G. Watson2

Introduction

This fast-growing palm tree quickly grows to a height of 40 feet, the smooth grey trunk topped with 10-foot-long, spreading green fronds. The inconspicuous white flowers appear from spring through fall and are followed by the production of bright red fruits that are less than one-inch long. The juice from these fruits can cause a skin irritation. Once highly recommended as a replacement for the Christmas palm, which is very susceptible to lethal yellowing disease, Carpentaria palm apparently requires a richer soil than many landscapes can provide. It is also susceptible to trunk cracks in cool weather, a condition that opens the trunk to decay organisms.

Use and Management

Carpentaria palm is probably best suited for an occasional accent or specimen planting where temperatures stay warm in the winter. A number of them grouped together can be attractive. Choose the best soil on your site for planting this palm.

Carpentaria palm should be grown in full sun on rich, moist but well-drained, fertile soil, and it has a low tolerance for salt and drought.

Propagation is by seeds.

Pests

Thrips.

Diseases

No diseases are of major concern.
