Commonly known as evergreen clematis, Armandii is a more rugged species with less-demanding care requirements. A flowering vine, Armandii blooms for several weeks in late winter in lovely, snowy white flowers. This clematis will climb over just about anything in its way, so either let it run free to scramble over shrubs and trees or train it to a trellis, arbor or other support structure. Install the structure before planting the clematis in the spring or fall while the weather is cool.
Find a planting location. Gardeners in areas with cool summers should plant the clematis in the sun and those with warm summers need to provide the clematis with afternoon shade.
Perform a soil pH test. Clematis thrives in soils with a pH between 6.5 and 7.0. Your county cooperative extension service can advise you on how to adjust your soil's pH.
Dig an 18-inch-deep hole, 6 inches away from the support structure, placing the removed soil in a wheelbarrow or on a tarp laid on the ground. Mix in well-rotted manure or compost until the removed soil is 50 per cent amended. Fill the hole with the amended soil until it is to a level where the clematis Armandii's roots will be buried 5 inches deep.
Place the Armandii's roots into the hole and finish filling it with soil. Water the clematis until the soil is saturated.
Tie the clematis loosely to the support structure.
