Most of the deutzias in cultivation are hybrids from parents of Asiatic origin.
They grow to around 2 m (6'6") high, with a similar spread.
In spring the young growth may require some protection to avoid it being cut back by spring frosts.
Clusters of pale pink, cerise or white star-shaped flowers appear from late spring to early autumn.
Week 18: Pot up cuttings taken the previous year into 150mm (6") pots of potting compost and grow on in the cold frame for another year.
Alternatively, plant them out into a nursery bed.
Week 32: Take semi hardwood cuttings from lateral shoots and pot up in a 50-50 mix of peat and sand and root in a cold frame.
Week 35 >: Prune back flowering stems after flowering, to ground level, to encourage new growth.
Week 40: Plant out in full sun or dappled shade anytime from now until April.
Avoid planting out in areas that are subjected to North or Easterly winds.
