|'Snowflake' is a very showy oakleaf hydrangea. The flowers can be up to 15 inches long panicles and appear to be double flowered due to multiple bracts or sepals emerging above older ones. The flowers can weigh down the branches but not as badly as some other cultivars.
H. quercifolia is a southeastern native that is often seen clinging to shallow soiled slopes in its natural environment. Form is deciduous and mounding. Grows to 6 foot tall and 8 feet wide. Leaves have 5-7 deep lobes that give leaves an oak-like shape. Fall color is bronze to purple and midsummer to fall flowers are creamy panicles. Sterile flowers turn pink as they age. To keep in good shape, remove any crossing or scraggly branches in winter or early spring.
