A glorious garden plant, Primula sieboldii (Siebold Primrose) is a deciduous perennial with slender stems bearing umbels of purple, crimson, pink or white flowers. Blooming from late spring to early summer, the dainty blossoms rise above a basal rosette of pale green, wrinkled leaves covered in short hairs. This primrose quickly establishes by self-sowing, without becoming invasive, and looks particularly beautiful planted in informal drifts. Hardy, it tolerates subzero temperatures, goes dormant during periods of extreme heat or drought, and resists some neglect. One of the best woodland primulas. Makes great cut flowers with a long vase life too.

  • Recipient of the prestigious Award of Garden Merit of the Royal Horticultural Society.
  • Easily grows up to 12-18 in. tall and wide (30-45 cm).
  • A part shade lover, it is best grown in humus-rich, 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.
  • A very versatile plant that can be used in beds and borders, cottage gardens, city gardens, rock gardens, or containers. Good edging plant too!
  • A low-maintenance plant. Tidy plant after flowering and remove diseased or damaged leaves.
  • Deer resistant but watch out for pests such as aphids, leafhoppers, vine weevil, and slugs. May be affected by gray mold (botrytis) or primula brown core.
  • Propagate by division as it comes into growth or by seed
  • Native from Eastern Siberia, Northeast China, Korea, and Japan
