Notes : Hydrangea (commonly called Hortensia) is a genus of shrubs and small trees native for most part of Southern and Eastern Asia, but there are also some native American species. They can be either deciduous or evergreen, but the most cultivated species that are used for decoration are deciduous. They flower all year long except in Winter. Usually their flowers are arranged in large round flower heads. In some species the nature of the soil can influence the colour of the flowers: on acidic soil, the flowers grow blue; on neutral soil, they grow off-white; and on alkaline soils the flowers turn pink or purple. Hortensias are moderately toxic if eaten, but in Japan and Korea, some species are used to produce a sweet tea.
