About this plant
This is a striking plant with a slightly loose upright growth habit and uniformly coloured very blue foliage. It will produce airy sprays of delicate brown flowers from late summer and the whole turns a cloudy and delightful bronzed gold in autumn. It can be subject to damage in heavy weather but is otherwise an accommodating and very useful ornamental grass.

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 in dry periods
Established plants in the ground can cope with 7-10 days of dryness, and shrubs often manage 2 to 3 weeks. Water one section of the garden thoroughly each day rather than a little everywhere. Check plants in pots more often, especially in hot weather.
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.
Winter
Winter - mid-late · Planting
Prune to the ground in winter
Cut foliage to the ground before new growth starts in spring.
Where stems are grown for ornamental value, they should be removed either before new growth starts in spring, or during winter when they begin to look ragged or untidy.
