Some things which you may be interested in about this rare plant which I have discovered through experimentation would suggest that it isn't as easy to care for as the general consensus stipulates.
It does not like tap water. It does not like rainwater (NW England rain anyhow). These turn the leaves brown very quickly. It took me a while to figure this out, but the only water it does like is bottled water, especially French - Evian or Volvic :D
It does not like the wind. Wind destroys the new leaves while they are still soft. These new leaves then go brown and look very tatty.
It does not like direct sunlight, whether it is outside or behind a window. The outer leaves scorch very easily!
It does not like to be in too big a pot. Despite being a clumping palm it would seem that if you put it in too big a pot it will go on strike and stop growing.
It's main growth is in the early spring. New shoots pop up and existing shoots will put out 2 or 3 leaves. Throughout the Summer it's growth will be slow. This would suggest temperate preference.
I have found it a tough battle to care for this palm and if i had the chance to buy it again i would probably pass.
