About this plant
A few of these distinctive plants are quite domestic in their appearance, for example the almost dainty Eupatorium hyssopifolium stands around 90cm high with heads of fine white flowers. In addition to the modest forms, there are the giants that classically tower at the back of broad borders which can achieve over 3 metres in height. They make strong vertical lines and are topped by soft broad domed heads of flowers in shades of mauve and pink as well as near red shades. The flowers come in summer and last into autumn.

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 - early-mid · Planting
Divide when too large
The plant can be divided if it becomes too large or another plant is required. This may involve physically dividing the clump in two, removing offsets or small bulbs or dividing rhizomes. The new plants can be grown in pots or planted in the ground.
