I try to keep an open mind, particularly toward plants I am neutral or negative toward.
@Springcolor found out about my aversion to primroses (squatty little plants that always revert to plain purple for me) and promptly gifted me a very delicate lilac primrose that is blooming now (really?) and has both retained its lovely color and nicely spread out for me. Voila, I now include primroses in my 'like' column!
