About this plant
This has a stunning display of flowers from July through to September. The flowers are held on long very thin stems which wave and even tangle above the foliage. The individual blooms are short, tight-clad oblongs and coloured a vivid dark red shade. The plant has an upright habit with paired oblong leaves on pinnate stems. The blooms contribute boldly to any planting and are sumptuous in a mass planting but could be used in a container. These may also be combined with grasses and plants such as rudbeckia in a mixed planting.

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.
