PRIMROSE 'JACK-IN-GREEN' MIXED COLOURS
Fresh seed of these old-fashioned curiosities is rarely offered. Each 'Jack-in-Green' flower has a tiny radiating ruff of leaves replacing the calyx, producing a beautiful posy effect. Flowers in many shades from yellow to deepest maroon.
Primula seeds may be sown in good light conditions at any time onto a loam-based compost, barely cover so that around 50% are still visible. We never use artificial heat, primulas are COOL germinators! As a rule best temperatures are usually between 10 and 15 degrees C. (e.g. a cool greenhouse or northerly window sill) PLEASE NOTE: Temperatures exceeding 15 C can prevent germination, and above 20 C expect very little germination as seeds can go dormant as a protective measure. Germination can take up to 6 weeks, but sometimes takes much longer.
