About this plant
This plant has strikingly coloured flowers. The rounded, fat petalled, close packed, daisy-like flowers are a warm orange-red with a domed golden heart. The leaves are rather rough, large and conical with wavy edges, coloured grey-green. The plant flowers from August until October. It can sprawl a bit so some discreet support may be beneficial. It is splendidly resistant to drought. It gets to around 2m (6ft) high with a 1.5m (5ft) spread.

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.
Summer
Summer-Autumn · Planting
Support tall stems
The plant may require support for long stems. Provide an artificial frame which it can grow through, or loosely tie the whole plant. A network of twigs can be woven together to provide a framework through which the plant can grow.
Tall stems can lean or be battered by weather. Support the plant to keep its vertical lines, aiming for a natural appearance which is easy on the eye.
