Primula is a genus with a wide distribution in many temperate and tropical regions of the world with a centre of diversity in the Himalayas. It is a large genus of around 350 species of herbaceous or semi-evergreen perennials that are organised further into various sub-generic groups. Members are characterised by a basal rosette of simple leaves and salver-shaped flowers on stout, erect stems. Primroses and cowslips are familiar wildflowers in this genus. Many Primula species have been cultivated and hybridised for 100’s of years leading to a plethora of available garden varieties. Primulas add beautiful colour to the winter garden and are very easy to grow. They are perfect for growing in containers and hanging baskets, or planted in borders or under trees in shady spots.
