Knowing what kind of hydrangea you have decides when you can prune it without losing next year's flowers. Our hydrangea identifier tells you from a photo whether yours is a bigleaf (mophead or lacecap), panicle, smooth, oakleaf or climbing hydrangea. It answers "what hydrangea is this" before you reach for the shears.
How It Works
Photograph the flower head along with several leaves; leaf shape is the most reliable clue, from the oak-like lobes of H. quercifolia to the glossy, coarse-toothed leaves of H. macrophylla. A shot of the whole shrub helps with habit and size. The result gives the species, pruning timing and notes on flower color.
Key Benefits
- Separates bigleaf, panicle, smooth, oakleaf, mountain and climbing hydrangeas
- Tells you whether the shrub blooms on old or new wood, which sets pruning time
- Explains why bigleaf flowers turn blue or pink depending on soil
- Dried flower heads left on the shrub in winter are often enough for a match
- Free web tool with one identification a day and no sign-up
