About this plant
This has small rounded flowers that tend to look downwards. They are coloured an intense deep purple, nearly black with a tiny white heart and rose-tinted stamens. The flowers are held on long branching stems above the hearty foliage mound. It is May and June flowering. These small flowers are very beautiful but can easily be missed, This is a good candidate for a shady spot by a seating area where the flowers can be closely observed.

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.
Spring-Autumn · Planting
Remove dead leaves
When leaves die they can carefully be detached or cut off at their base to improve the overall appearance of the plant. Be careful not to damage the main stems during this process.
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.
