Cornus controversa · Accepted scientific name
Scientific literature: Very Sparse (0 studies) · ★☆☆☆☆
Cornus controversa, commonly known as the giant dogwood, is a striking deciduous shrub or small tree prized in landscaping. One of its most defining features is its lush foliage, which provides a rich texture to any garden setting. The leaves are typically elliptical or ovate in shape, displaying a deep green color during the height of the growing season. As autumn approaches, these leaves undergo a dramatic transformation, turning brilliant shades of red or purple. This seasonal change in the leaf makes the plant a standout specimen for visual interest throughout the year.
