The palm grows to a height of 3-4 ft under good indoor growing conditions. Sentry Plam belongs to a group of palms (called feather palms) which produce fronds which are divided on either side of the midrib into leaflets. Curly Palm has a thin, slender trunk with feather-shaped drooping fronds which produce wide leaflets. The trunk is dark-green when young and turns brown as it ages. The canopy of a mature palm can spread 5-10 ft in diameter. This palm's fronds are more drooping and is generally smaller than its close relative Howea forsteriana (Kentia Palm) which grows to a height of 8 ft.
