This is a very nice palm to grow, don't let the z11 rating keep you from trying it. I have had 2 growing in ground under a large live oak for more than 5 years, 1 from a seedling and the 2nd has 5' of clear trunk. When temperatures dip into the low 30's, which is rare, there may be some spotting.

The Betel Nut Palm has been a very rewarding addition to my garden. It establishes very quickly here in Naples, FL. I planted mine about 5 years ago, from a small, 10 gal. specimen. It is now over 15 feet tall, and producing many fruits. The flowers are very fragrant, which was a pleasant surprise. The ripe fruits turn yellow, and look very much like miniature versions of the Samoan Dwarf Coconut's yellow husks.
Here in South Florida, I've found this palm to be extremely easy to grow. Actually, I've found that it needs a lot of winter irrigation here. Our winters are very dry, and considering that our soil is little more than sand with limestone gravel, things dry out quickly. Other than needing plenty of irrigation, it is not demanding at all. It responds well to a slow-release palm fertilizer, which I supplement with Fish Emulsion, and it stays a deep, emerald green all the time. Small plants will get a little burn on the leaves from our winter cold spells, but mine never lost any leaves due to cold. It is my guess that this is actually more of a zone 10b palm. I highly recommend this species. It is very ornamental in every aspect, it is self-pruning, and very fast growing. Don't hesitate to give this fun palm a try.

In Vietnam, you can see the older generation chew on this plant, like baseball player chew tobacco here in the US. I've seen women put a brown dye on their teeth so that when they chew this plant it won't stain the teeth red. The custom of chewing betel nut is unique to Vietnam. Old health books claim that it will make your mouth fragrant, decrease bad temper, and making digesting food easier.

I have two Betel nut palms planted for about a year, being in zone10a, Port Charlotte. Fl. They may not handle the winter cold fronts that occur from time to time. We'll see if they can take frost which is rare occurence here.

I really can't use the positive or negative rating as I am trying to find out how to propagate the seed. I've heard all the horror stories of oral CA from the chewing of the seeds. That is not my intent however. I thought the palm was lovely and want to container grow a couple. Now I'm stuck without proper guidance to grow. Does anyone have a germination clue for me? If I can sprout one then I'll tell you everything I learn along the way.

Nice looking palm for the tropics, but contrary to another comment, there is not one growing in Calfornia (save perhaps in a protected microclimate like a greenhouse or atrium, which hardly counts as growing in California) and certainly not one setting seed (must be a misidentification). Has been tried many times here and not even a glimmer of success so far. To those who claim this can grow outdoors in a garden situation, please show a photo!
Chewing on the seeds will also cause a yellowish stain around the mouth (a common sight in tropical Asia).

This palm is famous for its the narcotic properties of its fruits. This palm is not frost tolerant, but it is cool-tolerant and there is an acclimated one in Southern California that has even set seed. Do not water it in the winter though, because it will rot, and have it in rich, but well draining soil, and/or fertilize it a lot more than you would with a regular palm.
This plant has been said to grow in the following regions:
Big Pine Key, Florida Broadview-pompano Park, Florida Cutler Ridge, Florida Keystone, Florida Naples, Florida Port Charlotte, Florida Kihei, Hawaii Maalaea, Hawaii
