Queen Palm Trees - Cold Hardy Palms

(Syagrus romanzoffiana)

Cold Hardy to 20 degrees (lower depending on the age and growth of the cold hardy palm tree), the Queen palm can grow up to 50 feet tall.

A few decades ago the queen palm was assigned the name Cocos plumosa. During the late sixties and seventies most experts began referring to it as Arecastrum romanzoffianum. Now this queen has been placed in the genus Syagrus, the species name became romanzoffiana. The following is detailed information on the cold hardy Queen palm.

Queen Palm Trees Overview

This palm has a smooth straight gray trunk ringed with evenly spaced leaf scars and topped with a large canopy of feathery fronds. The fronds are dark green and have double rows of leaflets. This palm is noted for its spectacular clusters of flowers and fruits. The flower clusters burst from large pods during the summer. In early winter, the green fruit clusters appear. The spherical-shaped fruit eventually turns bright orange, hanging in clusters up to six feet in length. In each fruit there is a single hard seed with three spots.

This stately, single-trunked palm is crowned by a beautiful head of glossy, bright green, soft, pinnate leaves forming a graceful, drooping canopy. The ornamental, bright orange dates are produced in hanging clusters and ripen during the winter months. The dead fronds are persistent and often require pruning to remove. It is popular in commercial or home landscapes planted in rows on 15-foot centers to line a street or walk, in clusters or occasionally as a specimen. The grey trunk is ringed with old leaf scars.

Queen Palm Trees Usage and Maintenance

Growing best in full sun, Queen Palm is most suited for acidic, well-drained soils and shows severe mineral deficiencies on alkaline soil. This disfigures the palm by stunting the young leaves and can kill it. Unfortunately, Queen Palm is frequently planted in alkaline soil and requires regular preventive applications of manganese and/or iron to help keep the fronds green. Potassium deficiency is also displayed on older fronds in well-drained soils. Quick-growing Queen Palm responds well to ample moisture and fertilizer and is slightly salt-tolerant. After planting Queen Palm in the landscape, growth is rapid. This palm is not affected by lethal yellowing disease.

Pruning off too many fronds at one time can cause the palm to decline. Growth often slows with new foliage aborting to display distorted leaflets. The trunk is also very susceptible to decay. Prevent injury to the trunk by keeping turf well away from the trunk.

Propagation is by seed and volunteers will often appear under fruiting trees.

Queen Palm Pests

Palm leaf skeletonizer and scale are problems for Queen Palm

Queen Palm Tree diseases

Ganoderma butt rot can kill Queen Palm. It probably enters the trunk most often through wounds in the lower trunk and roots. There is no control for butt rot, only prevention.
