About this plant
Upright branching green stems carry small heads of flowers with a ring of bracts at the base. These are short and spiky, coloured dark red, often near-black at their tips. The centre of the bloom (the umbel) is dark pink to red and composed of many tiny individual flowers. This compact plant flowers during June and July. Note: Once the first flush is over the plant can be cut back hard to the ground. It should be fed and well-watered whilst it regenerates to deliver a further show in September.

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.
Summer
Summer - mid · Outdoors
Feed after cutting back
If the plant is cut back to the ground after flowering. Give a general purpose feed at this time to encourage new growth to develop.
Summer-Autumn · Planting
Prune young growth after flowering
When the plant has finished flowering, remove the flower and most of the young growth that the plant has made. Leave just around 2 centimetres of young growth on the plant. Don't cut into old wood unless it is diseased or damaged.
Planting & general
Planting
Deadhead blooms during flowering season
Remove flowers as they turn brown and fade. Snip the stem just below the bloom. This will keep the plant tidy and encourage more flowers.
The removal of spent flowers encourages the plant to produce fresh ones, rather than spend its energy on the development of seeds.
