PRIMULA VERIS SSP MACROCALYX
This is a significantly more robust and vigorous form of the common "cowslip", with strong stems of fragrant, deep yellow flowers in April to May, which are perfect for naturalising in rough, damp grassland, or on a sunny bank. The larger-than-normal flowers have attractive orange markings at the base of each petal, and protrude further out of the larger-than-normal green calyx.
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.
