Caracteristics and Pruning

Leaf-stem twiner. The roots are delicate, be cautious while planting. Clematis atragene are resistant to frost and against clematis wilt. They also tolerate dryness to a degree. The growth is moderately vigorous and the moderately dense foliage will last from April to October, with filigree leaves. Growth height is approximately 2 to 4 meters. "Blue Birds" flowers are lavender blue with 4 + 4 petals as seen on the photo above, and the flower is completely opened. The color fades to steel-blue, the flower diameter is 6 to 8 cm, the flowering period is April - May (the flowers are frost-resistant), and a second flowering may occur in August or September. The seed capsules are filigree and decorative. "Blue Bird" is multiplied by cloning to preserve the flowers unique characteristics. The plant should be pruned in May right after the flowering, by taking out some of the shoots.

Wire rope trellis for clematis

Chose a close grid wire rope trellis with a 25 - 35 cm wide mesh. Vertical lines should dominate, so that the trellis forms standing rectangles instead of squares. There is a table with suitable trellis shapes at the bottom of the pages. The 5050 wire rope trellis is a good choice and can be used with steel rods. Simple designs ("Basic" and "Basic-S") are enough, sometimes the "Mini" or light kits may be sufficient, but a trellis in the medium range allows for optimal development.
