Picture a shady glen with lots of moisture. Then put a large drift of Japanese primroses into the picture and you have created a beautiful scene. Japanese primroses are not difficult to grow if you can give them the shade and moisture they need. And, make no mistake, these primroses like moisture! Give them the correct conditions and they will reward you with a lush rosette of heavily textured cabbage-green leaves that persist until mid summer, and a stalk of white to red flowers that bloom in tiers along a tall stem. If you have a wet spot in your garden that gets shade in the summer, this is a great little plant.
