Heavy pruning isn’t needed, but can be shaped immediately after the early summer bloom. Flower color will be affected by soil pH, with purple-blue coloration in acidic soils with good aluminum availability and pink flowers in more basic soils.
Tuff Stuff™ Red Mountain Hydrangea
Closely related to H. macrophylla, H. serrata has very similar cultural requirements but better flower bud hardiness for improved blooming. Tuff Stuff Red hydrangea’s flowers open to a two-toned green and red and then mature to dark red-pink. The lacecap flowers first appear in early summer, and continue to bloom through the summer. Flower color will be purplish in more acidic soils. This is an excellent choice for climates where bigleaf hydrangeas struggle to overwinter.
