Flower Coloring Pages: Hydrangeas are flowering plants that belong to the Hydrangeaceae family. They are native to Asia and North and South America, thriving in temperate and subtropical environments. Known for their clusters of vibrant flowers, hydrangeas come in a variety of hues, including white, pink, blue, and purple. These flowers are unique because they can change color depending on the soil's pH level. Acidic soil produces blue flowers, while alkaline soil yields pink or purple blooms. Hydrangeas are typically deciduous shrubs, although some species are semi-evergreen or evergreen. They are favored for their large, showy flower heads and lush foliage, making them popular choices for home gardens and floral arrangements. With proper care, hydrangeas can be long-lived and provide beautiful displays of color throughout the spring and summer months.
