About this plant
This is a showy half hardy annual grass. It is, in fact, a form of ornamental millet. It is an F1 hybrid and will not set seed. It develops sturdy upright stems that carry large arching shiny leaves. These start green, or greenish, and the whole plant gradually turns purple, the colour being strongest and best in good sunlight. In July, August and September it sends up long slender flower heads that are coloured brown and look rather woolly and intriguing. The flowers are carried in some numbers and are highly picturesque.

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.
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.
Winter-Spring · Planting
Protect from winter cold
Bring the plant into a frost-free area before frosts occur, and do not put them outside until all danger of frost is past. Follow watering instructions, or allow the plant a period of dormancy during the winter.
Plants need to be brought inside in cold areas, i.e. colder than zone 8.
