Hydrangea is a genus of flowering plants known for their large and showy blooms. These plants are native to Asia and the Americas and are particularly popular in gardens and landscapes due to their striking appearance. Hydrangeas typically produce flowers in clusters, which can be spherical or flat-topped, and come in a variety of colors including blue, pink, white, and purple. The color of the flowers can sometimes change depending on the pH of the soil; for example, more acidic soils can produce blue flowers, while alkaline soils tend to yield pink blooms. Hydrangeas thrive in well-drained soil and prefer partial to full shade, although some varieties can tolerate more sunlight. They are relatively easy to care for and can be propagated through cuttings, making them a favorite among both novice and experienced gardeners. In addition to their aesthetic appeal, Hydrangeas are also used in floral arrangements and can be dried for long-lasting decorations.
