Rooguchi, commonly known as solitary clematis, is a non-vining, multi-stemmed, herbaceous perennial that grows with support to 6-8' tall and to 3-4' wide. It is a cross between C. integrifolia a shrubby clematis and xdurandii a vining clematis (some authors say C.
Clematis are hungry, thirsty plants. Water regularly in dry weather and feed with a high potash fertiliser, such as a tomato feed, just before they start to bloom. This is particularly important when growing clematis in pots. The feed should encourage a healthy crop of flowers.
Treat this flowering vine as a perennial vine for sun in the North. But it can take a bit more shade than can many other types of clematis; in the South, it is a good idea to give it partial shade.
Jackman's clematis prefers fertile, well-drained soil. A major soil consideration in growing Jackman's clematis is to keep the soil relatively cool. If the soil gets too hot, it is bad for the vine's roots. Cooling the soil is normally done by shading the base of the clematis with other plants or with stones.
Annual pruning may also be required to keep clematis plants looking their best. Pruning clematis helps plants remain both attractive and full of flowers. The type of clematis vine grown dictates when and how it should be pruned. For example, early spring blooming varieties should be pruned back as soon as possible following their blooming but before July, as they bud on previous season’s growth.
