Hydrangea paniculata 'Fire Light'
Upright cones open pure white and transform to deep pomegranate red as the season ages. Strong stems that never need staking.
The leaves and flower buds contain a cyanide compound. It is rarely a problem for people, but it is listed as toxic to dogs, cats, and horses, so keep prunings away from animals that browse.
For gardeners who like to stay ahead.
