I have found that plants that were treated with BAP to increase before sale were less hardy or vigorous. I have lost many dozens of plants over the years in their first two years in my garden, and I can not decide if it is their being EVR, or treated with BAP that made them disappear so fast. Too many growers breed for flower size, color, shape, form, etc., etc., at the expense of plant performance. Too many expensive "annuals" are being sold. I do not want to get a greenhouse to enjoy my favorite flower.
