    I planted two Buddleja Buzz Sky Blue in mid-summer 2014 and was so pleased with them that I added 11 more in 2015. I chose them for their drought tolerance, profuse flowering habit, and long period of bloom (July - frost). They stay reasonably small (maxing out at 5 feet tall and wide) and appear to be sterile (no little ones). The flowers are a lovely shade of blue/violet, and the butterflies love them.

    Large full blooms on a dwarf size butterfly bush....
    Each time I see the color of this beautiful bloom it reminds me of the beautiful blue sky I see at least 300 days out of each year at my home!
