Modern Major Miracle


Clematis 'Jackmanii'

In 1862, the first modern, large-flowered clematis hybrid was introduced, Clematis ‘Jackmanii.’ This cross between C. lanuginosa, C. viticella and C. x hendersonii was a huge success with its striking violet-purple blooms. A climber, it can reach 10 feet in height and have a spread of 3 to 6 feet. It is hardy to Zone 4 and starts its bloom cycle in midsummer. This clematis blossoms on the year’s new growth, and thus benefits from pruning in the late winter or early spring.
