I found two of them on sale this summer. I have been reading different discussion here in different forums. There are two discussing this plant in the Tropical forum
Recomended Palm ?
The thread "Recomended Palm ?" in
Tropicals forum
and
Palms and Cycads
The thread "Palms and Cycads" in
Tropicals forum
From what I have seen we will never see a big plant growing them in a pot. They are saying they get really big in the ground but still it takes years and years to get much growth.
