Not really certain where this came from - it's been a valued member of the "family" since before 1990, and started out as a seedling.
It now resides in an 18 inch wood slat basket, charcoal mix, hanging high in the greenhouse. It likes lots of light and lots of water, so when it got too big for its 12 inch slotted pot, I opted for the basket. It is prolific, doubling its size each year. An overgrown 12 pot sized plant was split in two and shared with a friend about four years ago. Today its foliage is a yard wide, and it puts up 9-12 inflorescences - in a good year, the flowers exceed a foot, vertical spread.
