Primrose flowers (Primula polyantha) bloom in early spring, offering a variety of form, size, and color. They are suitable for use in garden beds and borders as well as in containers or for naturalizing areas of the lawn. In fact, when given the proper growing conditions, these vigorous plants will multiply each year, adding stunning colors to the landscape. Blooming often lasts throughout summer and in some areas, they will continue to delight the fall season with their outstanding colors. Most primrose flowers seen in gardens are Polyanthus hybrids, which range in color from white, cream and yellow to orange, red and pink. There are also purple and blue primrose flowers. These perennial plants prefer damp, woodland-like conditions.
