After primroses stop blooming, dig up the plants and divide. Reduce root damage during division by holding each clump in a bucket of water and gently washing away soil from the roots as you carefully tease roots apart. Discard the old plant in the center Read more
Primroses can be sold from seeds and can be grown either indoors or outdoors. Seeds are generally sown indoors during the winter months. Once they've sprouted their second or third leaves, they can be transplanted outdoors to the garden.
primrose oil is sustainable. Primrose oil production is relatively sustainable since there is no known significant damage to air, water, land, soil, forests, etc. as long as pesticides have not been used.
Colonies of water primrose form dense floating mats on the surface of the water. Water primrose has fibrous, fleshy root with small bladders filled with air (they increase buoyancy in the water).
Water primrose has waxy, oblong leaves with pronounced veins and smooth edges. Its stems have a reddish tinge, especially in later summer, and often stand up off the water's surface.
They are easily propagated by lifting and dividing the large clump into several smaller ones and replanting them. Use a hand-held trowel or small shovel to dig gently around the plant to reveal the root system.
