About this plant
This is a handsome plant that is an annual or a short lived perennial. It makes a mound of long leaves with oblong lobes along their sides. The foliage is handsome with a pale-grey central rib, otherwise coloured light-green and definitely prickled. The beautiful flowers nestle amongst the foliage. They are big, cup shaped, poppy-like blooms, white with a satiny look. At the heart there are small creamy-yellow stamens, stained red at their base. The flower may flop a little. If one deadheads regularly there is a summer long floral display. If the flowers are allowed to stay interesting seed capsules follow. Give this sunshine in a soil that is poor to reasonable and well drained. The plant reaches around 1.2m (4ft) height, sometimes more, with equivalent spread.

Water during dry periods
For plants in the ground, when there has been little or no rain for a period of 7-10 days and the soil is dry, give it a deep watering and repeat weekly until there is a downpour of rain. Check plants in pots more frequently, especially in hot weather.
