Our most prolific and reliable blooming mophead hydrangea to date. Let's Dance ¡Arriba! ® hydrangea is a H. macrophylla x H. serrata hybrid with large, dense mophead flowers. It is so prolific you can finish and sell and flowering plant in the same year you pot up trimmed liners. The rich flower color ranges from hot pink to purple-blue, depending upon your soil pH, phosphorus and aluminum levels. The blooms age to an attractive mauve pink. Recommended as a replacement for Let's Dance Big Easy, Rave, Rhythmic Blue, and other first-generation reblooming hydrangeas.
