PRIMULA JAPONICA 'MILLAR'S CRIMSON'
These lovely candelabra-type plants shoot up numerous strong stems bearing tiers of deepest crimson flowers. The basal rosettes make the most spectacular, cabbage-like giants when well fed or in moist soil, and being bone hardy they increase in size yearly and will even self-seed, but never ever become a problem.
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.
