Hydrangea serrata are small deciduous shrubs similar to H.macrophylla and usually with lace cap flowers that are flat with small flowers without petals in the centre and showy flowers with petals on the outside. Native of the mountains of Japan and part of South Korea were it grows in mountainous woodland.
The Flower colour of Hydrangea serrata will vary with soil type.
Most Hydrangea serrata form round bushes between 1m and 3m tall.
Pruning Hydrangea serrata varieties.
Remove dead heads in spring (late March/early April), and thin out weak and dead stems. You can thin the brown stems to get larger flowers. Do not prune in the autumn as the old flowers give some frost protection to young shoots in early spring. The brown flower heads also look great in winter when covered in frost. If you need to shorten the plant always cut above a bud.
