I bought this last year at Lowe's. It was a small 6-inch plant but it grew and grew and bloomed and bloomed for months.

I pruned it back in January and this is how it looks now - it's twice the size it was last summer. I'll definitely propogate this one this fall. (I'm not that great with this digital camera - the plant looks better than these pics show. They are covered in water droplets also.)

I have 7 more different ones now - once I saw that the plant liked my shady patio here at the beach of SoCal, I went nuts!
