I'm so glad to know it's a new plant for some.
Very easy to grow, even where it freezes if protected.
I would think the plant is available world wide, but seeds are
economical, & germinate easily.
Be sure to see the slideshow on the page with the
plant care....

Better than mine, as you can see the size
compared to the home, & how it fits in with other plants, e.g.
bougainvillea...another favorite of mine.
