Clematis plant

This article discusses a brief history of the clematis plant, with a focus on the genus Clematis. Clematis is easy to care for, takes up little space, and pops up in gardens. With its fragrant flowers, it is one of the most popular plants for an indoor setting. For gardeners, it is a staple plant for providing color during the early spring.Be very gentle when settling the plant into its new home; the roots, crown and emerging vines of clematis can be easily broken. Position the plant slightly deeper than it was growing in the pot, so the first set of true leaves is just under the soil surface. Water weekly for the first season, to help the plant get established. If you can get your clematis through its first year, chances are good that it will continue to thrive. Mulching around the base of the plant will help conserve moisture, but keep the mulch several inches away from the crown, where the vines emerge from the soil.


Thorncroft Clematis, published their catalogue of 2000 with 8 subdivisions of clematis which was refined by 2006 to 16, those being Armandii, Atragene, Cirrhosa, Diversifolia, Flammula, Florida, Forsteri, Heracleifolia, Integrifolia, Montana, Tangutica, Texensis, Viticella, Early Large Flowered, Late Large Flowered and Species. For the most part the gardening public can understand these groups easily and yet this grouping system also offers enough diversity to divide clematis into meaningful groups for classification purposes. The RHS published its International Clematis Register and Checklist 2002 which acknowledges Wim Snoeijer of The Netherlands as the proposer of some of these new groups and he also influenced Thorncroft Clematis in the way their subdivisions were established.If left unpruned, a young, newly-planted clematis may produce a few long single stems with flowers only at the tips of each stem. To encourage multiple stems and a fuller habit, prune newly planted clematis vines the first spring after they were planted to about 12 inches above the soil level. This can be done in February or March. Be sure to cut each stem just above a bud. Once the stems start to grow in the spring and summer, the new growth should be spread out so that it is spaced evenly on the support and tied in place. Pinching out developing young shoots once or twice will promote further branching.

Group 2: Blooms twice: In late spring/early summer and again in late summer. Prune in late winter and again after the first flush of blossoms in spring or early summer. This group consists of many of the large-flowered hybrids and is the trickiest group to prune because the plants bloom twice during the growing season. In general, the spring blossoms occur on last season’s wood and the summer blossoms occur on new shoots. The goal of pruning this group is twofold: (1) retain a healthy framework of old wood and (2) stimulate new growth in order to maximize flowering throughout the growing season. Timing is everything.Group 3: Blooms in late summer/early fall. Prune in late winter. This is the easiest group to prune. Group 3 clematis vines flower in late summer or in fall on new growth that was produced that season. They send forth new growth from the base each year and can therefore be cut back hard on a regular basis. Simply cut the vines back to about 1 foot from the ground. If left unpruned, the members of this group will continue growing from where the growth ended the previous season. This will cause the plant to become top heavy. Moreover, flowering will occur at the tips of each stem, leaving a bare base. Representative plant selections in this group include: C. viticella, C. x jackmanii, C. integrifolia, and C. terniflora.
