Niobe (red) Clematis is a large bloom variety with blooms reaching 5-6 inches across. They are deep red but do tend to fade a bit as the blooms age. Blooming begins in late spring and continues through late summer. Avoid heavy pruining until the plant is well established then you may prune it in the winter. You may want to prune only half of the branches so that you will still have early blooms on the old wood.
Clematis are popular, perennial, ornamental vines that come in many flower forms and colors. Plant Clematis near trellises, rock walls, or any other structure that the vines can climb up. Hummingbirds are attracted to the abundant blooms while deer and rabbits tend to stay away.
Pruning Group 1 – Include the early flowering varieties. These typically will bloom on the previous year’s growth. In winter or early spring, remove dead or damaged stems and trim back slightly or not at all.
Pruning Group 2 – Includes the varieties that bloom in mid-season and have large flowers. These will set buds on the growth from the previous year during the early season bloom and then on current new growth later in the summer. To prune, remove dead or damaged vines late in the winter or early spring. Cut these varieties back about 6-8 inches or where you see a couple of strong buds. Strong buds appear to be bumps on the stem just above a spot where the vine branches. Leave about an inch above the buds.
Pruning Group 3 – Includes the late blooming varieties that have large flowers and small flowers. These will bloom mid-summer into the fall on the current year’s growth so they require the most severe pruning. In late winter or early spring, before new growth begins, cut down to 6-8 inches above the ground. Look for a place where the stem changes color and cut 1-2 inches above that or to a set of buds near the ground.
