Thanks for the comments, guys! Glad you like it as much as I do.
FWIW - I checked my records and it was an import. I got it from Floralia back in 2011. It's not a fast or robust grower but once it gets large enough to bloom...it's worth the wait. Now that I think about it, I have 4 perrinii and none of them are rampant growers so I would say it's just the nature of this species.
