SKU: 1208-10
Primula japonica, the Japanese primrose, Japanese cowslip, Queen of primroses, or valley red, is a species of flowering plant in the family Primulaceae, native to Japan. The plant prefers shady, damp, poorly drained conditions such as those found at the edge of streams and ponds. The species is a herbaceous perennial, growing to 45 centimetres (18 in) tall and broad, with clusters of flowers on erect stems, emerging from rosettes of leaves to 25 centimetres (9.8 in) long, in spring. The plant produces scapes which are 2 feet (0.61 m) high.
The main flower color for this plant is deep red-purple, though there can occasionally be pink and other colors.
Type: Hardy perennial
Hardiness zones: 5-8
Seeds per pack: 10
Note: Ornamental use only. These seeds and/or plants are poisonous.
Germination: Start indoors. These seeds require light to germinate. Sow the seeds on surface and water in. Do not bury the seeds. Leave them at room temperature (20-22 °C, 68-72 °F) for 4 weeks. If they have not germinated after 4 weeks then a cooling period is required. Cover them with plastic and place in a fridge for 4 weeks. Be sure they stay moist. After the cold-moist stratification period they are then brought back to a cool room (15C, 59F) for them to germinate. Germination can be 30-90 days after the warming period, though some will take longer.
