How to Grow Primrose Flowers

Perennial, Primula

Primrose is a hardy perennial with a wide range of varieties. Native to Asia, Europe, and North America (originally found from the Midwest to the Northwest U.S.), primroses fall into two garden groups: those for bogs and woodlands, and those for rocky areas, cliffs, and hillsides. Some prefer rich, wet soils; others like it dry. Most varieties grow 8–15 inches tall.

Primroses come in a wide variety of colors, in single blooms or clusters, with sweet-smelling flowers. They bloom throughout summer. New plants typically bloom in their second year.

Primrose flowers attract hummingbirds. They're excellent for hillsides and as ground covers.

Plant Height: 18″ – 24″

Plant Propagation

Primroses are grown from seed and don't transplant well. Direct-sow into your flower garden, hillside, or ground cover area. Sow seeds early in the season and cover lightly with soil. Spacing varies by variety—check the seed packet; if unavailable, use 12–15 inches as a guide.

Days to Germination: 10–15

How to Grow Primrose Plants

Primroses are easy to grow. They prefer cool weather and full to partial sun. Soil conditions vary from rich loam to average soils depending on variety. Mix in plenty of leaf mold before planting. Add leaf mold annually as mulch and fertilizer. Drought-tolerant varieties are popular as ground cover in dry areas.

Once established, primroses bloom all summer with little attention. Expect first blooms in the second year. Being very hardy, they survive light frosts before going dormant for winter. They don't require mulching or winter protection.
