Infrared close-up photo of a garden Primula cultivar with bright orange flowers. A dusting of small dew drops rest on some of the flower petals.
Primula species have been extensively cultivated and hybridised, mainly derived from P. elatior, P. juliae, P. veris and P. vulgaris. The term Polyanthus (often called P. polyantha) refers to one such group of plants, which has produced a large variety of strains in all colours, usually grown as annuals, and available as seeds or young plants.
