About this plant
This superb grass forms a large clump of dark green foliage with flower spikes that rise upwards and outwards to over 2m (7ft). It is a beautiful and worthwhile garden plant, when seen against the light, it is one of the glories of late summer. The delicacy of form and brilliance of colour is unequalled in the big grasses. It needs a specimen site as it is such a beauty and may be seen to good effect at Hilliers Arboretum, Hampshire. If grown in a garden, remember that it needs a lot of room for this display and that, year on year, the foliage clump will expand.

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 - 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.
