About this plant
Ethereal in flower, dainty in appearance but in fact a hearty plant that generally stands around 1.5 metres in height but can reach over twice that height in optimum conditions. It has an appealing growth habit with somewhat tiered layers of rounded leaves, held in horizontal sprays. The flowers are held in long light-looking brown-red columns and form a hazy spray of tiny lilac tinted blooms with prominent yellow stamens that protrude from each of the tiny dancing blooms that hang, heads lowered, from the slenderest stems. This flowers during July and August and needs placing against a quiet, uncluttered background so the flowers are lost in a medley of shape and colour. If conditions are too rich this may need staking so resist the temptation to feed and nurture to excess.

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.
Spring-Autumn · Outdoors
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.
Spring - late · Planting
Divide when too large
When the plant is too large clumps may be divided into two or more pieces. Rhizomes can be cut, whilst small bulbs or offsets are detached. The new plants can be grown in a container or planted in the ground.
Summer
Summer-Autumn · Planting
Support tall stems
The plant may require support for long stems. Provide an artificial frame which it can grow through, or loosely tie the whole plant. A network of twigs can be woven together to provide a framework through which the plant can grow.
Tall stems can lean or be battered by weather. Support the plant to keep its vertical lines, aiming for a natural appearance which is easy on the eye.
