Hydrangea Quercus from Germany blooms like snow in Chenshan Botanical Garden

Just after eating zongzi in the Dragon Boat Festival, the high temperature came to Shencheng The summer "three treasures" of short sleeve, cool mop and ice watermelon are entering people's daily life with irresistible momentum This summer's three treasures can really make us forget the heat for a short time, but it's cool to be calm, so it's a good choice to observe a plant carefully Recently, in the nursery of Chenshan Botanical Garden in Shanghai, oak leaf Hydrangea from Germany have many snow like flowers under the shade of the trees If you are willing to bend over to enjoy them, you may get a "little cool" Hydrangea quercifolia W Bartram is a deciduous shrub of Hydrangea (some taxonomic systems divide the family of Saxifragaceae, while Hydrangea belongs to Hydrangea) It originated in the south of North America It was discovered and named by William Bartram, a taxonomist in the 18th century Quercifolia is a Latin word for Quercus and Folium, Quercus is a genus of Quercus in the Fagaceae Family, and Folium is the meaning of leaf The combination of the two is Quercus leaf, whose English name is oakeafhydrangea At that time, William Bartram thought that the shape and division of Hydrangea leaves were similar to that of some oak plants, so he gave her the name, which was simple and clear In addition to the special leaf shape, the inflorescence type of Hydrangea Quercus is also rare in this genus, because most of the inflorescences of Hydrangea are umbrella like and corymbose, such as the common h.macrophylla, the whole inflorescence is like a ball, while the hydrangea Quercus is cone-shaped, a little like the ice cream cone (h.paniculata inflorescence is also cone-shaped) Compared with Hydrangea, the color of her flowers will not change with the pH value of the soil, but will change from white to pink with the flowering time The hydrangea of oak leaf likes half shade or shade, which is suitable for planting in weak acid soil The flowers are as white as snow when they are first released In the hot summer, when we encounter such flowers in the shade of the trees, we must also be able to calm down and listen to this wonderful song of plants.
