Nursery contributed plant descriptions

Satiny, saucer shaped flowers of glowing ruby, with a blood red centre, wave on fine leafy stems throughout spring until the heat of summer. Seemingly delicate, this North African annual prefers exposure and poor, hopefully alkaline, well drained soil but will grow just about anywhere that is not shaded, the flowers only open in direct sunlight. My favourite winter annual, it never fails to impress with a depth of colour seldom matched and is lusted after by all who see it it in the nursery. Press seeds on to lightly raked bare soil, do not cover (they need light to germinate), where they are to grow in autumn or early winter. Will self sow in light soils but will probably need the assistance of a light raking with the first rains in heavier soil. Each pack contains in excess of 50+ seeds.
