I picked up Garden Show this summer at a box store and was so pleased with how it performed. The bloom period seemed to last quite a while, usually had multiples open at a time, and the blooms were stunning - bigger than my hand and just gorgeous. I can't wait to see how it performs next year after having time to settle in. It looks to me like it is already spreading, as I saw new fans popping up near the end of the season.
It was a "I'm not going to buy any plants today" trip, until I caught it out of the corner of my eye and literally whipped my head around and texted my husband to say I'm sorry but I'm buying plants today
This is the pic I took and sent him to explain why I couldn't possibly pass it up, and a Passion For Red ended up on my cart that day too.
