Shades of primrose-cream with red spots.
Tolerates most soils, though it prefers a rich light well-drained soil in full sun or partial shade.
More and lusher leaves are produced when the plant is growing in a rich soil, though less flowers are produced. When grown in a soil of low fertility the leaves are smaller and less lush, though more flowers are produced. The plant will also succeed in very poor soils. It dislikes drought.
This species is not frost hardy in Britain but it is often grown in the flower garden as an annual when it will frequently self-sow.
