PRIMULA JAPONICA 'POSTFORD WHITE'
This hardy, long-lived plant will become enormous in rich moist soil, producing yellow-eyed ivory white flowers on thick, strong stems, and is almost certainly the most impressive of all of the tall white primulas.
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.
