Robust and vigorous, Primula japonica, commonly known as Japanese Primrose, is a deciduous perennial with attractive whorls of flowers in shades of white, soft to deep pink, purple or red. They are spaced at intervals along upright stems and rise above basal rosettes of lettuce-like, bright green leaves. Native to Japan, this perennial thrives in damp, shady environments where it brings in late spring or early summer its brightly colored blossoms. Primroses are brilliant vehicles for adding color to the shade garden.
- Easily grows up to 12-18 in. tall (30-45 cm) and spreads up to 12 in. (30 cm), this plant quickly establishes to a good size by self-sowing and looks particularly beautiful when grown in mass. While winter-deciduous, it will return with vigor year after year.
- A part shade lover, it is best grown in humus-rich, consistently moist, neutral to acid soils. This plant may be grown in full sun in cool summer areas, provided the soil remains moist. Mulch this plant to help maintain the soil moisture and keep the roots cool. Wet soil tolerated.
- This plant is very versatile and can be used in partially shaded beds, borders, in cottage gardens, containers or along streams, ponds or water gardens.
