The plants are starry, with whitish hairs. The leaves are rounded and ash-coloured. The fragrant flowers are white, cream yellow, pink, red, purple or blue. The flower is widely used as an ornamental plant for summer discounts and as a cut flower and aromatic plant. It is grown in the ground for the spring ornament of the gardens or in pots. It is very suitable for the cracks in the reefs of the marine locations. The species has been in culture since at least the 16th century.
