繡球花Hydrangea

名八仙花，種植需特別注意濕潤度。花朵形成聚傘花序，多形成如其名繡球般的圓狀，花為紅、藍、粉、紫等鮮豔色彩，會因環境酸鹼性而有所不同，因此被稱為天然的酸鹼指示劑。

Special attention needs to be paid to the moisture level when planting. The flowers form umbel inflorescences, often forming round shapes resembling their name "ball," and come in bright colors such as red, blue, pink, and purple. The colors may vary depending on the acidity or alkalinity of the environment.
