Foliage remains bright green throughout the year. The leaves twist around the stems, hence its name.
What to use it for
In a conifer bed or as an architectural feature (particularly for the distinctive twisted leaves).
How to look after it
Requires little maintenance.
How to prune it
You shouldn’t find that much pruning is required for this plant. Remove any dead, diseased or damaged growth in autumn or midwinter as necessary.
How to propagate it
Semi-ripe cuttings can be taken from late summer to early autumn and should root readily.
Seeds, which may not come true from this cultivar, can be collected from female cones as they ripen (which will take a year) and brown in autumn. Store them dry then stratify in damp peat in the fridge for 3 weeks before sowing with bottom heat of 15-20˚C.
If the plant is too small to yield sufficient material for cutting, and if you have the skills to do so, it can be grafted with a spliced side-veneer graft onto pot-grown rootstocks. Keep the graft at 20˚C for a few weeks until the callus forms.
Generally free of pests and diseases.
