Blue Boy was an odd find at Lowe's for me one year. I was surprised to see they had something other than the usual white, red, and lavender varieties. I scooped it up and gave it a home in our Rhodi bed. It is a dense plant so far and ours is about 3' tall. I think it came in a 2C pot and it was planted spring of '12. It's flowers are a pretty medium purple with darker spotting on the top. The growth is moderate at about 4-5" a year. It is cold/wind hardy in the winter and summer heat tolerant. Ours is butt up against other rhodi's but on the NW side of our home and doesn't burn from the winter.
