Cardoon Overview

Cynara cardunculus is also known by the names Globe Artichoke, Cardoon and Prickly Artichoke. It is a herbaceous perennial species in the daisy family, Asteraceae (Asteraceae). Typically growing to around 2.5m tall, this species produces spiky, semi-divided silver-grey leaves up to a metre long. Flowers are large and showy, coloured purple and they are thistle-like in appearance. These appear from late summer-autumn. This species has earned a Royal Horticultural Society (RHS) Award of Garden Merit. It is also part of the RHS “Plants for Pollinators” initiative to showcase plants that support pollinator populations by providing ample amounts of nectar and/ or pollen. A great choice for encouraging pollinating insect wildlife into your garden!
