A lovely very hardy little rockery flower that can be grown along borders, rockeries and probably pots.
Will self-seed but will not become invasive. Mine was already in the garden and has proved to be a great attractant to all sorts of insects ie hoverflies, bees, all types of flies, other little bugs seem to like them too.
Mine is on the rockery, in full sun, in sandy soil and does very well. Flowers throughout the summer.
