They make great house plants. I grew one for 7,8, years or so in the house. Big pleated leaves,dark green. One problem you might have is thrips. Mine was totally pest free for years..then tiny black thrips showed up. I finally had to break down and use systemic poison. But it worked perfect.
I planted it out in spring..doing fair. Some new small leafs. That's another story.
Anyways check out my Santol pics of a few years ago on Dave's Garden.
