About Clematis montana Buch.-Ham. ex DC.
Clematis montana, commonly known as mountain clematis, Himalayan clematis, or anemone clematis, is a flowering plant belonging to the buttercup family Ranunculaceae. It is a vigorous deciduous climbing plant. In late spring, it becomes covered in a mass of small blooms that last for approximately four weeks. The scented flowers are white or pink, have four petals, and feature prominent yellow anthers. This species is native to mountainous regions of Asia, ranging from Afghanistan to Taiwan. Clematis montana is a popular garden plant grown in temperate regions. It can scramble up and over unsightly structures such as sheds and fences. If left unpruned, it can reach up to 12 m (39 ft) in size. This plant attracts bees, butterflies, and hummingbirds. Many varieties and cultivars have been developed for horticultural use, including C. montana 'Alexander'; C. montana var. grandiflora AGM, which bears larger flowers than the original species; C. montana var. rubens 'Broughton Star' AGM, which produces double, deep pink flowers; 'Elizabeth', which has pale pink flowers; 'Freda'; 'Pink Perfection'; 'Tetrarose' AGM, which has deep pink flowers; and C. montana var. wilsonii, which flowers later and has chocolate-scented blooms. Any cultivar marked AGM has earned the Royal Horticultural Society's Award of Garden Merit.
