High Quality Content by WIKIPEDIA articles! Ravenea rivularis is a species of flowering plant in the Arecaceae family. It is found only in Madagascar. The extremely elegant, fast-growing majesty palm has upward-arching leaves that are divided into long, thin fingers. It makes a fine conservatory feature plant, but make sure the roof is high enough, because, in the right conditions, it can get quite tall. Relatively easy to grow, it tolerates low light and cool conditions but needs decent summer humidity- a dry atmosphere can be fatal. Water well over summer, but only when the surface of the potting mix dries, and add a liquid fertilizer every two weeks. Keep just moist in winter. (Rosenfeld 257)
