About this plant
A dainty plant that could easily be lost in a busy garden. This has slender upright stems that carry horizontal sprays of delicate blue-green leaves. The leaves are flat and smooth in appearance, held on threadlike stalks and having neat rounded lobes. It flowers, rather discreetly, in early summer when the light greenish yellow flowers, held in small sprays, appear. (In some places the flowers have been recorded as being dull purple.) It needs a position in a raised bed or a nook in a rockery where its gentle, elegant character can express itself.

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.
