I grew mine from seed, and it flowered this year. It is about that
size in a 7.5" pot filled with rich, sandy loam. Other than blowing
over, it seems happy, and is not as tender as I thought.

Any fruit, Nick? Or is it not self-fertile? I couldn't make sense of
what I found googling, as both seem implied on different sites.
