What is King Protea

The King Protea (scientific name: Protea cynaroides) is an evergreen shrub of the Proteaceae family native to South Africa. In its native habitat, it is widely distributed in the southwestern and southern fynbos regions, preferring acidic, nutrient-poor, well-drained environments. Known as the "King of Flowers," it is a representative species of the protea and is the national flower of South Africa. It is also referred to by its scientific name, Protea cynaroides. The plant requires a long cultivation period, taking about five years from sowing to shipping. The shrub grows to a height of 1-2 meters.

The leaves are leathery, thick, glossy, ovate, and alternately arranged. The flower can withstand drought and blooms year-round in its native habitat, but it is sensitive to humidity and blooms in Japan from April to December, excluding the summer months. The inflorescence is a head-shaped flower with a diameter of 12-30 cm, consisting of more than ten rows of sepals (involucral bracts) and comes in pink, red, and white colors. The pink, red, or white structures that appear to be petals are actually involucral bracts, with the true flower being the mass of stamens inside the bracts. The stamens rise from the outside and bloom towards the center. In its native habitat, birds like the Sugarbird (scientific name: Promerops) and beetles act as pollinators, making it both an ornithophilous and entomophilous plant.

As a tropical plant, it is commonly used in flower arrangements in hotels and restaurants in places like Hawaii. Although it used to be rare and expensive in Japan, it has become more widely imported recently and is frequently used in luxurious flower arrangements.

Similar Flowers
A plant similar to the King Protea (scientific name: Protea cynaroides) is the Pincushion (scientific name: Leucospermum spp.) of the same Proteaceae family. Protea belongs to the genus Protea, while Pincushion belongs to the genus Leucospermum.

Origin of the Name
The genus name "Protea" is derived from the Greek god Proteus, who could change his form at will. The species name "cynaroides" comes from the resemblance of its flower head to the artichoke (scientific name: Cynara scolymus) bud.
