Caryopteris× Clandonensis likes light and is also tolerant to half-shade, drought, heat and cold. It can survive in the open field safely in the area above -20℃.According to observation, the drier the weather is and the more intense the light is, the more golden the leaves are.If under the condition of semi-shading for a long time, the leaves are yellowish green.It is noteworthy that the root, the root neck and the adjacent branches of the cortex perishable Browning, causing plant death.Water less in the rainy season to prevent floods.Caryopteris× Clandonensis can grow normally under the condition of annual rainfall of 300-400mm, soil pH value of 9 and salt content of 0.3%, it is more tolerant to barren, and it can still grow well in the area of steep slope, heavy gravel and poor soil fertility.
Caryopteris× Clandonensis mainly grows in temperate coniferous broad-leaved mixed forest areas in North, Central, East and Northeast China (main cities: Harbin, Mudanjiang, Hegang, Jixi, Shuangyashan, Yichun, Jiamusi, Changchun, Siping, Yanji, Fushun, Tieling, Benxi)
