Veronica...I thought I went to extremes to grow some of the plants I love, but I think you've got me beat! Only because I hadn't thought of some of the measures you are taking...
I was brand new to brugs last year, but had what I consider to be a measure of success, since I only had a slight clue as to what I was trying to do. That measure along with the fact it looks as though I may have successfully wintered over at least one (out of two) has empowered me, so now I need more!
I ordered two cutting on eBay last year from a recommended vendor. Expectations were low, based on where I live, but I got blooms!
Not sure if the first was labeled correctly as it is listed as a double and bloomed as a single, but I don't care...It was gorgeous!
Labeled as American Pride
