About Clematis armandii Franch.
Clematis armandii Franch., commonly known as Armand clematis or evergreen clematis, is a flowering climbing plant in the genus Clematis. Like many other species in this genus, it is valued by gardeners for its showy blooms. It is a woody perennial that is native to most of China, excluding northern China and the extreme south of the country, as well as to northern Burma. This plant attracts bees, butterflies, and hummingbirds. When grown in cultivation, C. armandii produces fragrant 2.5-inch white flowers in spring, which bloom on growth from the previous year. Its dark green leaves droop to create a textured appearance, and it works well as a screening plant. It can reach a maximum height of 20 feet. If grown in salty soil or water, the tips of its leaves may develop severe burn damage. In the United States, it grows best in American Horticultural Society zones 7 through 9, which are generally located in the southern United States. Known cultivars include the pink-flowered 'Hendersonii Rubra', as well as 'Apple Blossom' and 'Snowdrift'. The 'Apple Blossom' cultivar has received the Royal Horticultural Society's Award of Garden Merit.
