About this plant
This is a name for a group of hybrids. They have shiny, toothy-edged leaves held rather horizontally on slender stalks. The plants make pleasing soft mounds of foliage, often with warm bronze or copper tints when they emerge in spring. The flowers, coming in July and August, are frothy and make oval or conical plumes, coloured in shades from white to deep red. You can dry the flower heads for winter use. An excellent plant for moist sites, attractive from spring to autumn in both foliage and flower..

AutumnNow
Autumn - late · Planting
Divide every 3 years
Physically divide clumps every three years, or the plant will flower and grow less well. Discard or give away unwanted portions, or replant them to make a larger display. Plants can sometimes take a while to recover from this procedure.
Spring
Spring - late · Outdoors
Feed with slow release fertiliser
Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)
This is a simple way to provide a nutrient boost as a single annual procedure.

Water to keep the soil moist
For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.
Without regular watering some plants never fully regain their beauty.
