Topic: Primula hybrid
Feedback from NBN Gateway:
You have a botanical error on your site.The "False Oxlip" is NOT P. vulgaris x P. veris - this cross is generally sterile. It is P. veris x P. vulgaris. Besides knowing this from experience, (I breed them, and did my PhD on my own plants) I would refer anyone querying it to D. H. Valentine, 1955, Studies in British Primulas No.4, Hybridization between Primula vulgaris and P. Veris; New Phytologist 54, pp70-80.
