Crisply serrate foliage, in misty blue-green, erupts from the ground in late summer and this impressive plant may even produce a totally superfluous waxy maroon-brown flower spike for you in hot summers
- Position: full sun
- Soil: moderately fertile, moist but well-drained soil
- Rate of growth: average to fast-growing

- Hardiness: half hardy (will need winter protection)

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.

Although it is is shrub, this plant is best treated as a perennial and cut down to within two or three buds from the base of in early spring. It will shoot back from the base. Protect with a dry winter mulch of straw or bracken especially in cold winters.
