About this plant
This has lively informal flowers for a long period from June to September. The flowers are held on brown stems and are coloured in shades of purple. The large heart of the bloom is coloured red-purple whilst the surrounding petals are light purple with a silken hue and often twist and curve. The leaves are rich green, large and tapering with impressed veins and some maroon tints on their edges. The flowers open from rounded hairy brown buds that perch on their leaves like edible Cape gooseberries in restaurant desserts. Deadhead regularly.

Spring
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 - early · Outdoors
Feed a general fertiliser
Where plants have moderate needs for nutrients, they can simply be given a general feed, fairly early in the growth season so that the growth has plenty of time to harden off before the cold weather.
Give plants a general boost with the application of a general purpose fertiliser which is spread around the root area of the plant, with amounts as directed on the feed label.
Summer-Autumn · Planting
Prune after flowering
When flowering has finished, cut the plant hard back removing all stems to buds that are 30cm to 45cm above ground level.
