Spathacea is a lovely Californian for a dryish spot, possibly a little shade. I used to have trouble establishing this plant so maybe it is not for beginners. I don’t think it would be good for humidity.
Spathacea has the most wonderfully fragrant foliage with a citrus smell. It is a hardy evergreen, usually fairly low, but if it was especially happy might reach a metre.
There are some colour variations, yellow etc but I have never got them going in my garden. After a year or so from seed they die off, no doubt to do with water.
