Clematis paniculata

A vigorous, woody, evergreen vine that can climb over 9m.

Juvenile foliage is trifoliate with lobed margins, whereas adult leaves have entire margins. Male and female flowers occur on separate plants. Star-shaped white flowers are produced through spring, followed by masses of attractive fluffy seed heads.

Prefers permanently damp but not sodden soil, in a situation where it can grow up into the sun. Let it scramble through other trees and shrubs to get to the light, but make sure its base is in the shade. This clematis will tolerate exposed conditions, but leaves will be smaller and thicker.

Prepare the planting site when soil is moist and easily worked, such as after the first rains in spring and autumn. Remove all weeds and incorporate bark, compost or other organic material. Before planting, ensure the root ball is saturated and remove the planter pot with minimal root disturbance. Trim any broken roots and plant at the same level as in the container. Dig a hole twice the diameter of the root ball, press in and water once planted. Plant with some general slow-release fertiliser and then every spring, apply an organic fertiliser (such as blood and bone) at a handful per square metre.

Climbing plants require similar types of maintenance as trees and shrubs. Apply an annual dressing (50g/m2) of general-purpose fertiliser. The first summer and autumn after planting is critical for young plants, so water thoroughly during dry periods. Mulching helps conserve moisture and suppress weeds. Organic materials, such as sawdust and bark, contribute to soil structure. Be sure to keep deep mulch away from plant stems.

Clematis is easily grown from seed. It can also be grown by taking cuttings, but these can be fickle and slow to strike.

Attracts bees and butterflies.

In humid climates, it can be prone to powdery mildew. It can be also prone to phytophthora in waterlogged soils. Protect young plants from slugs and snails.
