perennial herb of Asian origin. It produces a basal rosette, consisting of large, green, roundish leaves with wavy edges, generally quite rigid and compact; they are covered with a thin hair, which can cause skin irritation in sensitive individuals. From autumn until late spring from the center of the rosette, a long, slightly fleshy, erect stem develops, bearing numerous five-petalled flowers, in shades of pink and purple. In fact, there are numerous cultivars, with more varied colors, still remaining in the shades of pink. These primroses are very common as houseplants, especially during the winter; they are often used as annuals, sometimes even in the shaded flowerbeds of the spring garden. The flowering is very prolonged, especially if one remembers to remove the withered flowers, these plants go into vegetative rest with the summer heat, and generally they start to bloom again towards the end of August or the beginning of October.
