First got one of these in 2009 under the Proven Selections category. Every year since then have gotten 2 including this year, its inaugural year under the Proven Winners badge. I see no difference but that's a good thing because these plants are unique, robust and very close to a true blue.
These do require a tad bit more maintenance than say, lantana or verbena but just some water, regular fertilzer and a little relief from unusually hot summer sun and this chap will bloom prolifically and continuously all summer.
One of my top 3 or 4 PW plants and would recommend if only for the unique shape and rich blue color.
