The sentry palm plant is a similar tree when comparing it with the kentia. The scientific name is Howea Belmoreana and it's also known as the curly palm. The fronds arch over more on the H.belmoreana and it grows slower, though.
The sentry is native to Lord Howe Island (Australia) and cultivated there. The seeds are also sent to and cultivated in other countries including, the Hawaiian Islands.This is a feather type palm that displays wide fronds, not as wide as the coconut palm but wider than the parlor (parlor is the most popular). Because the fronds grow wide and the tree can grow well over 8ft tall - a suitable displaying space is required, such as a hallway or hotel entrance. Like most palms in the right setting this looks fantastic.
Water when the soil begins to lose its moisture and use a good drainage pot for the plant to grow in.
A fast draining soil mix is best to use which is likely to be part sand and/or perlite for easier drainage.
Fertilizing every month from spring to summer is appropriate with a general or (if available) palm fertilizer.
Room temperatures of around 65°f / 16°c - 75°f / 24°c are ideal. The temperature should not decline lower than 55°f / 12.7°c.
