About

Ptychosperma elegans, commonly known as the solitaire palm (or elegant palm after the scientific name), is a very slender palm endemic to Queensland in Australia. In the nursery trade and in the United States it may be confusingly referred to as Alexander palm, which is an often-used but misnomered name of another Australian palm species Archontophoenix alexandrae, the Alexandra palm (note the difference in gender between the two names).

How to grow it

The tropical species is a popular palm in gardens and parks, where its arched crown, slender trunk, and red fruit are regarded as appealing feature. They are less successful in cooler climates and somewhat to susceptible to frosts. Plants grown in pots or indoors require high amounts of light with humid and warm conditions. A blight that covers leaves with dark brown patches, especially in sub-tropical climates, does not seem to interfere with a specimen's growth.

Ptychosperma elegans is cultivated as an ornamental tree for planting in temperate climate gardens and parks. It is a single trunked tree, that in cultivation can reach 20–40 feet (6.1–12.2 m) in height.

Where it grows

The species is endemic to Queensland, Australia, where it grows in both tropical and sub-tropical rainforests as an understory tree, often close to rivers and streams where there is plentiful water and good drainage. Its altitudinal range is from sea level to 900 m (3,000 ft).
