I have had this plant for two years. It blooms beautifully in the spring, but not again. It grows, but does not rebloom. It get lots of sun and partial shade. I bought another plant this year that was in bloom. It, too, has not had more flowers. Any suggestions?

Beautiful hydrangea and blooms consistently for me

I have had this plant since early spring of this year- repotting it in May from a 3 to a 5 gallon and keeping it on a deck where it gets high indirect light and direct Southern sun for about 4 hours daily. It has flowered non-stop from mid-May until now- August 2 and shows no signs of slowing down- though the heat has consistently topped 94 degrees and humidity as stayed at 75% and above. Needless to say, I am very, very impressed with its vigor and its flower show! I would give this an A+ for being a tough little flowering machine.

I planted two of this variety last year along my front walkway (facing east with midday to evening shade). I was anxious to see how the plant would do in its second year and I must say I am absolutely thrilled with the abundance of blooms and the plants lovely shape. Granted this spring's wet weather has allowed for ALL my various hydrangeas to look nice, but the Twist-n-Shout has exceeded my expectations so far. I have since added 4 more to my landsape.
