I bought it the first year when I wasn't set up to keep good records. I think I bought it from Alicia at Williamson Flower Farm (http://www.williamsonfarmflowe...). Mine has not bloomed yet....hopefully this year (bought late in 2013).
Leslie, you have a really nice collection of SAs! I'm especially enjoying the Burseens...I like them too...but you have to really hunt to find photos of some of them!
