Beccariophoenix Fenestralis (Giant Windowpane Palm) is a rare, exotic palm that resembles the Coconut Palm. It is native to the rainforests on the east coast of Madagascar. The young leaves are a beautiful grass green and have slits in their center, resembling windowpanes. When mature, the fronds of this Madagascan palm expand up to 16 feet long, with stems as tall as 40 feet.

Although this species of palm is endangered in the wild, widespread, commercial distribution of its seeds since 1990 has resulted in an increase in its popularity among collectors and botanical gardens. And because it prefers a humid, tropical climate, it is an excellent choice to grace Hawaiian island homes.

Beccariophoenix Fenestralis (Giant Windowpane Palm) Growing Tips*

Beccariophoenix Fenestralis (Giant Windowpane Palm) is a fast-growing, extremely hardy palm that can withstand wind and full exposure to the sun. In fact, the more humid the climate, the faster it grows.

With that in mind, follow these general palm-tree growing tips to ensure your Giant Window Pane Palm has a long and healthy life.

• Situate the palm tree in low-traffic areas to avoid being brushed against too often. This weakens the leaves.
• Repot when the palm becomes completely pot-bound. This will slow down its growth if you want your palm tree to remain indoors for as long as possible. Consider transplanting tall-growing palms outside to allow them to reach their full height. Allocate up to 50 feet of space out from the trunk for the root system to spread.
• Plant in well-draining soil; soggy soil encourages fungus growth. For potted palm trees, an all-purpose potting soil (), works well. Thoroughly loosen the soil where you intend to plant outdoor palm trees, removing weeds and rocks to ensure good drainage.
• For potted plants, use a fertilizer designed especially for palm trees. Have your soil tested to determine what nutrients, if any, it needs to ensure the best growing environment for your outdoor Beccariophoenix Fenestralis (Giant Windowpane Palm).
