Clematis 'THYRISLUND' old man's beard, clematis

Thyrislund is a fabulous large flowered, semi-vigorous clematis found by a Danish grower Flemming Hansen. He claims no credits for its breeding, and confirms that the plant was one of many that arrived from England without a label. Unable to trace its origin he gave it a name of his region, and began propagating it. Its flowers are about 12 cm across, light lavender violet with pointed tips, semi-double in spring, and single in late summer.

It belongs to Group 2 clematis: in early spring remove dead and damaged stems before growth begins, trimming all remaining stems to where strong buds are visible. These buds provide a framework of second-year shoots that flower in late spring and early summer. We suggest pruning the plant after the spring flowering has finished by about a third or even half its size. It will re-emerge and flower again and quite reliably from August until October.

Clematis likes deep, fertile, moist but well-drained soil that remains cool. You can grow a plant below clematis that will provide shade for its roots. Add garden compost in late winter and mulch it well. Fully hardy to min. -34°C (USDA zone 4).
