Hydrangea (Diamond Rouge #2)
This variety has abundant, long lasting, rounded flower heads that start white and progress to pink, intense raspberry red and finally wine red. Flowers start blooming in July and take on red coloration earlier in the season than other pink paniculatas. Flower color is best in the fall when night temperatures are 10 degrees cooler than day temperatures. Compared to Strawberry Sundae®, Diamond Rouge® is slightly bigger and has distinct raspberry-red flowers that color earlier in the season. Benefits from multiple prunes in production to produce strong stems. Flower color varies based on climate and growing conditions. Bred by Jean Renault in France.
Hydrangea are a genus of about 70-75 species. They are native to Asia and (through fossil evidence) North America. They can grow as vines and as trees / shrubs. Most of the climbing varieties are not hardy here and require a lot of sun to be successful. The shrub versions do well here depending on species. I do not recommend 'Endless Summer' varieties here in the prairie. They can survive here but the rate is lower than I would recommend. Some were brought back to Europe by a Dutch Indies trading ship in 1736.
Flower petals grow as sepals, which is a leaf design that protects the plants. They like moist but not wet roots (hydro meaning water). Hydrangea are incredibly hardy and will revive even after severe drought damage. Prune like other woody perennials - usually in the fall. New shoots will grow from the old wood the following spring. I have a lot of luck just pruning off the flowers as the heads die back, which also maintains a very clean appearance.
Most hydrangeas will change color over the season - sometimes slight and sometimes dramatic. Some will change color based on the pH of the soil and the presence of copper (usually will shift a pink hydrangea to blue). The paniculata varieties generally change from white blooms to red towards the fall.
