Culture Notes
Reseeds easily.  Seeds can be collected in the summer and sown under glass in the early spring.  Division of the clump can be done once dormant.  Does well if planted alongside stream banks or pond margins.  This plant will even grow in water.  Likes boggy ground locations.  Japanese Primroses are among the easiest to grow, featuring wrinkled foliage and brilliantly colored flowers.

Most Primula species resent hot, humid weather and boggy conditions.  Contact with the hairs on its foliage may irritate the skin.  Do not mist foliage, as its hairs can trap water and result in unnecessary rotting and/or gray mold (botrytis).
