Hardiness: half hardy
As they unfurl in early spring, the spectacular, grey-green leaves up to 50cm (20in) long, reveal serrated edges that look as though they have been cut with pinking shears. This dramatic architectural shrub makes a stunning specimen for a sunny, perennial border or exotic-style garden in warmer areas of the country. In hot summers, it sends up curious tubular, reddish-brown flowers, but it is the wonderful foliage that stops you in your tracks. To stop it getting leggy, it is best cut back in early spring and the plant will make up to 1.5m growth in one season. To minimise the risk of frost-damage it's important to provide a dry, winter mulch. It is quite late into leaf in spring, so you do need to be patient, but you may be surprised by the amount of growth it will put on late in the year.
