Hydrangea, Tinted

The greatest diversity of hydrangea species exists in eastern Asia, which includes Japan, China, and Korea. The color of hydrangeas, except for white hydrangeas, depends on the acidity of the soil. You can make pink hydrangeas turn blue by increasing the acidity of your soil. You can increase the acidity by adding coffee grounds, citrus peels, and crushed eggshells. Hydrangea flowers bloom in a variety of different formations. The most popular are the mophead hydrangeas, whose flowers grow in big ball-shaped clusters. Lacecap hydrangeas, which grow well in shade, have clusters of tiny blooms accented by larger blooms. Panicle hydrangeas, which grow well in cold, have flowers that grow in cone-shaped clusters. The name hydrangea comes from the Greek words hydros, meaning water, and angos, meaning jar, which is fitting because these plants require a lot of water. However, too much water can kill them. Signs of overwatering include wilting, yellowing leaves, leaves falling off, and stunted growth. Hydrangeas are often given on 4th wedding anniversaries to symbolize appreciation and heartfelt emotion.
