Is the hydrangea toxic? What should be noted when caring for it
The hydrangea is toxic. In people's imagination, the hydrangea is as tempting as cotton candy and seems non-toxic, but in fact, once a hydrangea is eaten, abdominal pain appears within a few hours. Other typical symptoms of poisoning include skin pain, vomiting, weakness and sweating, and there are reports that patients may even experience coma, convulsions and collapse of blood circulation in the body. Fortunately, an antidote for hydrangea poisoning has now been developed. As for smelling it, it will not cause poisoning; its scent is in fact not very noticeable, and as long as you do not eat it, you will not be poisoned.
The hydrangea is produced in Yunnan, Guangxi, Guangdong, Fujian, Taiwan, China and other provinces and regions. It grows on plains or in mountains, attached to trees or rocks; it is cultivated in gardens both domestically and abroad.
The hydrangea is native to our country and Japan. It was introduced to the United Kingdom in 1736. In Europe, it is relatively commonly cultivated in the Netherlands, Germany and France, and hydrangea varieties in colors such as red, blue and purple can be seen in flower shops. There are also quite a few hydrangeas planted in the ground in small gardens and in front of buildings.
At present, the German company Rampp · Jungpflanzen is a world-famous enterprise producing hydrangeas, and is also the main breeding and production unit for new hydrangea varieties. Next, the Dutch company Moerheim · Van Waveren and Israel's Yag Nursery are also major hydrangea production enterprises. In Asia, Japan is mainly abundant in hydrangeas, and in gardening shops there is a wide variety of hydrangeas, where many new varieties with unusual flower colors can be seen, expensive and all used as household potted ornamentals. At present, hydrangeas have an annual output of 2.7 million pots and an output value of 17 million US dollars, ranking twelfth in Japan's potted flower output value. In the Americas, cultivation is mainly relatively common in the United States, with a certain number of both potted and outdoor plantings.
Our country cultivated the hydrangea relatively early, and hydrangeas were planted in the Jiangnan gardens built during the Ming and Qing dynasties. The parks built in the early 20th century also could not do without the arrangement of hydrangeas. Modern parks and scenic areas all plant them in large patches to form landscapes. However, the potted ornamental use of hydrangeas is still not very common, which brings an excellent opportunity for the development and application of hydrangeas.
Although the hydrangea is toxic, as long as you do not eat it, poisoning will not occur. Here, special reminder should be given that families with children should avoid planting toxic flowers such as hydrangeas.
