Caryopteris is a half hardy to hardy deciduous shrub that grows to around 1.2m (4ft) high with a similar spread.
In colder areas of the UK, plant out against a house wall to offer some protection.
The grey green leaves are aromatic, and clusters of blue bell like flowers appear from August to September.

Cultivation;
Week 13; Pot up rooted cuttings into 70mm (3") pots of potting compost.
Grow them on in a cold frame until planting out time.
Week 14; Cut out previous year’s growth hard back to young healthy buds.
Weak or damaged stems should be cut out to ground level.
Week 32; Take semi hardwood cuttings and place them in a cold frame to root.
Week 38; Plant out any time from now until March in a sunny spot with well drained soil.
In exposed conditions it may require some form of protection during the winter months, against a south facing wall or fence would be ideal.
