Dense umbels of light sulphur-yellow flowers bloom from July to Sept over rosettes of toothed, bright green foliage. These long-lived, easy-to-grow plants are natives of the damp regions of the Caucasus Mountains and are very tolerant to sun as long as they have adequate moisture.
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.
