perennial herbaceous of Asian origin. It produces a basal rosette, formed by big leaves of green colour, roundish, with wavy margin, usually quite rigid and compact; they are covered by a thin down, which can cause skin irritations in sensitive subjects. From autumn until late spring, from the centre of the rosette, a long, erect stem develops, slightly fleshy, with numerous five-petalled flowers, in shades of pink and purple.
In fact, there are numerous cultivars of various colors, but always maintaining 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 shady beds of the spring garden. Flowering is very long, especially if you remember to remove the wilted flowers, these plants go into vegetative rest in the summer heat, and generally begin to flower again towards the end of August or early October.
Exposure is a very important factor to take into account if we want to grow our own plants. A wrong location, in fact, could have disastrous effects on the growth of our primrose. Let’s see together then what are the main cultural needs of this species.
