PRIMULA X KEWENSIS
Created in the early 1900's at Kew gardens, this quite incredible hybrid between Primula verticillata and Primula floribunda is fertile and comes true from seed. It bears heads of brightest lemon yellow on strong stems above rosettes of deeply-crinkled leaves, all of which are heavily covered withv attractive white farina. However it cannot breed with either of its parents and is a most beautiful stable cross which unfortunately produces only a small number of good viable seeds here.
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.
