Primula candelabra Hybrids

Sowing:

The seeds of candelabra primroses germinate at 15-20 ° C; higher temperatures can hinder germination. Sow on the surface of a moist, well-drained special sowing compost. Cover with a pinch of vermiculite without completely covering the seeds. Place the whole in a mini-greenhouse or a transparent plastic bag in a shaded area. Keep the compost moist but not waterlogged. Germination usually takes 10 to 30 days. Once some seeds have emerged, sprinkle the compost with a thin layer of sieved compost to facilitate the rooting of the seedlings.

Transplant the young plants into 8 cm (3in) pots when they are large enough to handle. Grow them in a cooler environment, giving them plenty of water—plant outside, with a spacing of 23cm (9in).

Cultivation:

Candelabra primroses appreciate relatively moist to marshy soils; a location near water suits them perfectly. Ideally, plant them in the shade, in a cool understory. Ideally, the soil will be deep, humus-rich, relatively neutral and slightly acidic, even peaty. You can plant them in cooler regions in full sun, but the soil must be kept moist throughout the year. Growing these species in pots and containers, in a mixture of compost and peat, kept wet throughout the year is also possible. Place the pot in the shade, exposed to the East or North.

Remove the foliage and faded flower stalks once a year, and divide clumps that have become too large. It is recommended to repot potted plants every two years to renew the substrate.
