Howea belmoreana

Belmore sentry palm is a single-stemmed, pinnate-leaved, evergreen perennial native to Lord Howe Island, Australia. It is a member of the palm family (Arecaceae). The genus name commemorates its island home, and the species epithet honors Sir Somerset Richard Lowry-Corry, 4th Earl of Belmore, governor of New South Wales. 

This feather-type palm grows at a very slow rate, which is apparent by the closely spaced trunk rings (leaf scars). When grown indoors, a height of 10 feet can be expected after many years, while in the wild heights can reach 40 feet. It grows at its best with bright, indirect lighting.  Too much light can cause the plant to yellow. Ensure that proper drainage is provided by planting in a fast draining potting mix. Allow the plant to dry out between watering and use only chlorine-free water, as it is sensitive to chlorine. The roots of this palm do not like to be disturbed. Repotting should only be done when the plant has become pot bound.  When repotting, caution should be used when handing the roots, which are brittle. It must be propagated from seed. When grown indoors, seeds are typically not produced.

Often confused with the kentia palm (Howea forsteriana), the Belmore sentry palm is much more slow-growing, smaller at maturity, and the leaves are distinctly recurved. Both species are endemic to Lord Howe Island, but the kentia palm favors coastal habitats, whereas the Belmore sentry palm grows at higher elevations.

This palm is suitable as a houseplant or greenhouse subject. It is not the easiest palm to grow. Other, easier palms include majesty palm and parlor palm.

Insects, Diseases, and Other Plant Problems: Temperatures below 28 degrees F can cause leaf burn. Full sun can damage the foliage. Root rot can occur when the potting mix is allowed to remain soggy. Cold drafts can cause the leaves to drop. Other issues include brown leaf tips, which are caused by dry air or under watering. Leaf spot can occur when overwatering and with a sudden temperature change. Monitor for mealy bugs, scale, and spider mites when grown indoors.
