Additional Information

The Jackman Clematis is a hybrid that has flowers with large, rich purple sepals, which develop on new growth. The root system should be kept cool by deep soil preparation and mulching around base. It is said that Clematis prefer "a warm top and a cool bottom". While this is generally true, provide some shade during the day to the top portion for best results. Climbs by twining stems and clasping leaves, so needs a trellis or wire support. Leaf spot and stem rots can be serious problems.
