One of the more vigorous of the candelabra group of primulas, this is also one of the very brightest, with flowers that can vary from magenta to pillar-box red. In time, in moist organic soil, these plants make strong impressive clumps.
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.
Common name:Primula cockburniana
