It is an annual herbaceous plant that grows up to one meter tall. The double and semi-double forms of this popular wildflower bloom in a range of colors (white, blue, red, pink, pink, light blue, violet, lilac and some can be spotted). It is very easy to grow and is fast growing and abundant. Adaptable to most good well-drained garden soils with plenty of sun. It is a hardy and undemanding plant that tolerates not very fertilized or rustic soils, so they usually sprout alone in the fields in full sun. They flower from mid-spring to the following autumn.
