A wildflower that is now often used in the garden where it is treated as a half hardy annual.

The variety of flower colours include white, pink, red, blue, lavender and yellow thus making it a useful plant for informal plantings in open sunny spots.

The dwarf types are just 150-200mm (6"-8") tall, whereas the taller varieties can reach 400-500mm (14"-18").

Some of the lower growing varieties are suited to baskets and containers.
