Hybrids with flower diameters of about 10 cm are described here as a separate clematis group. Their magnificent flowers are just as beautiful as those of the large-flowered hybrids but the flowering lasts longer. According to the rule of thumb "the smaller the flower, the more robust the plant", these clematis hybrids are also less susceptible to disease and less maintenance-intensive and therefore often better suited as façade plants. They are a junction to the clematis viticella group. Please note that while some of these clematis only need a small trellis, some can grow to over 4 meters in height. Read the overview to find available clematis.
These clematis thrive in partial shade locations, don't plant them near any hot south or east walls! The soild must be fresh, humus rich and well drained with no standing water and as sheltered as possible from the wind. The trunk base must be in shade. Planting distance: 1 - 2.5 m. Position the roots 10 cm below ground level when planting. Use a 12 liter pot for bucket culture. The available varieties can be found overview.
The clematis are frost-resistant and perennial leaf stalk twiners. They grow with moderate vigor, with foliage from May to October, up to approx. 5 m in height and often just as wide. The flowering lasts longer by cutting off the flowers and preventing the development of seeds, the clematis will respond by opening new flower buds. The seeds are beautiful in autumn, but the withered leaves don't detach by themselves and need to be cut at the end of the year. Cut the stems down to approx. 20 - 60 cm over the ground. The medium sized clematis are less susceptible to mildew than those with larger flower. The varieties that carry a lot of viticella heritage are particularly healthy.
For clematis, chose a close-meshed trellis with a 25 cm to 35 cm grid, and more vertical than horizontal lines so that the shape resembles "standing rectanbles" instead of squares. There is a table with suitable designs at the end of the page. Our wire rope trellis 5050 with steel rods is a good choice. Simple designs ("Basic" and "Basic-S"), as well as "Mini" or Light can be used, but the Medium range allows optimal development of the plants, especially if mildew or clematis wilt are an issue. The heavy / massive design ranges give the plant more space with a bigger distance to the wall wich helps in preventing clematis wilt and mildew.
