What type of Protea flower is this?

'Protea cynaroides', also called the king protea, is a flowering plant. It is a distinctive member of Protea, having the largest flower head in the genus. The species is also known as giant protea, honeypot, or king sugar bush. It is widely distributed in the southwestern and southern parts of South Africa in the fynbos region.

The king protea is the national flower of South Africa. It also is the flagship of the Protea Atlas Project, run by the South African National Botanical Institute. The king protea has several colour forms and horticulturists have recognized 81 garden varieties, some of which have injudiciously been planted in their natural range. In some varieties, the pink of the flower and red borders of leaves are replaced by a creamy yellow. This unusual flower has a long vase life in flower arrangements and makes for an excellent dried flower.

The king protea grows in a harsh environment with dry, hot summers and wet, cold winters. Several adaptions include tough, leathery leaves, which helps to prevent excessive loss of moisture, and a large taproot that penetrates deep into the soil to reach underground moisture. Like most other Proteaceae, the king protea has roots with dense clusters of short lateral rootlets that form a mat in the soil just below the leaf litter. These enhance solubilisation of nutrients, thus allowing nutrient uptake in the low-nutrient, phosphorus-deficient soils of its native fynbos habitat.
