Clematis Henryi (Dormant Bare Root) hardy Large-flowered Vine,Perennial
Dormant Bare Roots in 3' Pots
We usually ship perennials to you in their dormant state, that is: bare roots, usually without leaves, in 3' pot of loose soil. They may have some shoots beginning to grow. It is very important to plant these dormant perennials as soon as possible after you receive them. If it is absolutely necessary to store them for a short time before planting them. If the roots appear dry, soak them for a few hours in warm water. Thereafter store in slightly moist soil in a cool, but not freezing location until you can plant.
Clematis ‘Henryi’ is a time tested favorite! Profuse, showy, eight-sepaled, 6-8″ in diameter, white flowers with purplish brown anthers cover this vine in summer. Blooms on this cultivar comes primarily from the previous year’s stems in early summer, but also occurs in a second flush later in the summer on the new (current year’s) growth. This clematis can be trained to climb a wall, trellis, fence, arbor, porch or lamppost. Can also be planted to sprawl over and through large shrubs or over old tree stumps Provides height and good architectural framework for small gardens. An excellent vine for long-lasting, often spectacular, summer bloom.
Pruning Group 2 – These cultivars produce early season bloom on the previous season’s growth and late season flowers on new growth. Generally, these cultivars are only pruned to shape. In the early spring (February or March), prune them lightly above the first pair of new swollen leaf buds, removing about 12 inches from each shoot. Also remove any dead or weak stems at this time.
Clematis are one of the most popular groups of garden perennials. These flowering vines can be worked over an arbor, threaded through other perennials or secured up a tree. Growing them is fairly easy. But pruning clematis tends to instill fear in the stoutest of gardeners. This fear is unwarranted, since pruning clematis simply breaks down to a question of when your clematis blooms. Plant bareroot clematis in early spring while the plants are still dormant
PLANTING CLEMATIS IS AS EASY AS 1-2-3
1. Loosen the soil to a depth of 12” and mix in several handfuls of compost and ¼ to ½ cup of all-purpose granular fertilizer (follow package directions).
2. Dig a hole deep enough for the roots, and position the clematis so the crown of the plant (where the roots meet the stem) is right at the soil line.
3. Cover the roots with soil, allowing the growing tips to be barely visible.
TIPS FOR PLANTING CLEMATIS
Though clematis like their “heads” in the sun, the bottom of the plant should be shaded so the roots stay relatively cool.
During the first growing season, your new clematis should be watered whenever the weather is dry. Mulching around the base of the plant will help retain moisture and keep the roots cool. Sometimes clematis need a little help holding onto a trellis or structure. You can use soft twine, waxed string or even zip-ties to attach the vines and provide extra support.
Prune clematis vines to encourage new growth, which results in more flowers.
No matter which pruning category your clematis plants fall into, flowering will diminish on all clematis vines without pruning.
Left unpruned the new growth is confined to the tops or ends of the vines and that is where your flowers will be
CARING FOR CLEMATIS AFTER THEY BLOOM
After the flowers fade, some clematis develop decorative seed heads. These can be left in place throughout the growing season. Though it's not necessary, you can also cut off the seed heads to keep the plant looking neat. Some clematis varieties bloom again in late summer or early fall. If you think your clematis could be a rebloomer, remove only the spent flower heads and avoid cutting back the foliage.
Early spring is the best time to prune a clematis. There are two approaches to pruning. Some varieties produce new growth on last year’s vines, so they should only be pruned to shape the overall plant. Others varieties die back to the ground. Since any new growth comes from the base of the plant, all of the prior year's vines can be removed. Until you get to know your clematis, it’s best to wait until the plant has sprouted new growth. That way you can see where it's coming from and prune accordingly.
Fertilize your clematis in the spring when the first leaves start to unfurl. Follow package instructions, sprinkling approximately ¼ to ½ cup of all-purpose granular fertilizer around the base of the plant.
If your clematis outgrows its space, you can control the growth by simply cutting back the entire plant to a height of 5". This can be done in fall or early spring. Stray vines may also be trimmed back any time during the growing season.
