code: 563
It bears heads of brightest lemon yellow

Family: Primulaceae
Plant Classification: Half hardy perennial Hardy perennial
Packet Content(approx.): 12 seeds

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 with 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.

Sowing advice:
Primula seeds may be sown at any time onto a loam-based compost, barely cover so that around 50% are still visible. Best germination temperatures are between 10 and 15 degrees C. (e.g. a cool, northerly window sill) PLEASE NOTE: Temperatures exceeding 15 C can prevent germination, and above 20 C expect very little germination as most seeds will go dormant as a protective measure. Germination takes between 3 to 6 weeks, sometimes taking much longer.
