Protea cynaroides (King Protea) - Shrub with reddish stems and large rounded green leaves to 3 to 5 feet tall and wide with huge 5-10 inch flowers. These pale silky pink or sometimes deep crimson flowers, form a roundish central peak of flowers surrounded by rays of darker pink bracts. Flowers cover the shrub from autumn to spring with some scattered bloom throughout the year. Plant in full sun in a well-drained, preferably acid, soil. Requires little irrigation and tolerates coastal conditions. Protect from frost and temperatures below 28° F. Cut flowering stems back to base after flowering. It is an attractive garden plant for a nice well-drained site in the garden or as a container specimen and a great cut flower for arrangements. This species has a wide distribution through the fynbos in the southern parts of South Africa, an area subject to wildfires for which Protea cynaroides is well adapted with its thick underground stems that have dormant buds that sprout up after a fire. It is the national flower of South Africa. The genus and plant family is named for the Greek god Proteus, who was able to change between many forms and reflects the incredible variety and diversity of the plants in the family. The specific epithet means like plants in the genus Cynara, the Artichoke, in reference to the like appearance of the flower buds. Other common names include Giant Protea, Honeypot and King Sugar Bush. We also grow a pure white selection called Protea cynaroidesa 'Arctic Ice' and a dwarf form called Protea cynaroides 'Mini King'. 

The information displayed on this page about Protea cynaroides is based on our research conducted about this plant from books in our nursery library as well as from information that is provided by reliable online resources. We also have included our own observations made about it as it grew in the nursery gardens and other gardens visited, as well how the crops of this plant performed in the containers when we had them in our nursery field. We also include comments received from others and welcome hearing from anyone who has information about this plant, particularly if it includes cultural information aiding others to better grow it.

 
We closed for regular business at the end of 2025 in order for the property to be developed for affordable housing.
Our gates remain closed but we will open them by appointment to interested parties as we liquidate remaining supplies and equipment.
