Marojejya darianii (Big Leaf Palm) is a small tree typically ranging between 10-20 ft in height. It is a slow-growing palm with ornamental foliage, closely related to other Madagascan genera, with many states likened to a tropical palm. It is exceptionally cold hardy and can be grown in USDA Zones 9-11. Native to the island of Madagascar, it needs shade or semi-shade to thrive, and soil that remains moderately moist.
When planted in colder regions, optimal potting care is essential. The pot should be placed in an area where it can avoid being exposed to the cold, ideally in a bright location but not direct sunlight. Sulphur or other forms of mulch should be added around the roots to introduce additional insulation. During the warmer months, it is best to let the soil dry out slightly between waterings, regular waterings to insure it has enough hydration to survive the winter cold. During winter, ensure that the plant is watered sufficiently so that the soil does not go dry.
Overall, Marojejya darianii (Big Leaf Palm) is not just an attention-grabbing species that looks great in a garden but also perfect for humid, tropical areas. With a little bit of extra care in colder climates, this palm can easily create a stunning display in any garden.
