About
This bushy, half-hardy annual, producing flowers in a range of colours from red, pink, yellow and orange. Each flower has a single outer ring of petals and a dome of florets in the centre, which resemble a scabious or peony. The flowers are held above mid-green foliage on stems up to 75cm (30in) high, making them ideal to grow for cutting.
