Hydrangea sargentiana
Bigleaf hydrangea is a deciduous plant which grows to a height of 2-3 meters. Its large, heart-shaped leaves are tinged with red in early summer and dark green in summer. Two-lipped, white to pink flowers appear in summer, followed by round, white, pea-sized seeds. This species is native to North America, growing in moist, deciduous forests, swamps, and riverbanks. It’s popular with butterfly and hummingbird enthusiasts, and is appreciated for its dramatic effect when blooming. It’s also an important source of cut flowers. Bigleaf hydrangea is a hardy, easy-to-care-for plant that will bring some color to a garden.
