Primula Jack in the Green Orange. Orange flowers enclosed in a cup of attractive green leaves which remain after the flower has faded. Primulas are a no fuss easy to care for perennial that loves shade to dappled sun. They do best the edge of the woodland, naturalising in the lawn or in containers. Flowering in spring but if cut back leaf and all after flowering they will usually re-flower right through until late autumn. Best to divide in winter and feed with lime and manure. Grows to 20cm.
