A very small species from Thailand with tough linear green leaves.
Thailand, think warm, so I was surprised that it tolerated a light frost last year (unintentionally)
though it didn't resume growth until temperatures really started to rise in mid-summer.
I have had to revise my opinion. It has really sulked after cold weather, although it has taken a long tome to show it.
It has now come indoors for the winter to preserve it.
This year it has been in a growing case to give it some warmth, and it has benefitted, though it is still having some problems.
