Hydrangea

Genus that includes both garden hydrangeas, which can also be grown in pots, and shrub hydrangeas. Among the former, we highlight H. macrophylla, with toothed oval leaves, globular or flat inflorescences of 15-20 cm, which grows in permeable and acidic soils, requiring little sun exposure and few prunings. Among the shrub varieties, we note H. petiolaris, called climbing hydrangea, and H. quercifolia, called oakleaf hydrangea, with white flowers gathered in upright panicles.
