How to Manage Pests

Pests in Gardens and Landscapes

Primrose—Primula spp.
Family Primulaceae

Plant Identification

Primroses are perennial plants. In areas with moderate winter temperatures, primrose may be grown as a winter annual. Plants form a basal rosette, and flowers generally bloom in the spring and are often clustered or tiered along the stem. Flower colors vary and include yellow, white, purple, pink, red, orange, blue, and brown.

Optimum conditions for growth

Primroses do best in areas with cold winters and cool summers. In cooler climates, primroses can tolerate full sun. In hotter areas, they need partial or full shade. Plant in rich, well-drained soil. An organic mulch placed around plants can keep roots cool. Most species require regular watering.
