Description

The king protea, in Latin Protea cynaroides, is the floral emblem of South Africa. It is a delicate, but spectacular and fascinating perennial shrub. This botanical species produces floral heads in the shape of large flared cups, formed by pink and velvety bracts surrounding a heart of powdery pink flowers with white. Flowering takes place from April to October, depending on the climate, and the flowers are very long-lasting in dried bouquets. Cultivation in large pots is essential except in very mild areas.

The king protea is a perennial shrub of the protea family. Widely distributed in South Africa, it varies in colour and shape, adapting to many mountain environments without frost. The plant, with sucker roots, develops multiple thick stems, branching from the base. It will reach between 40 cm and 1.20 m in height, and will slowly spread over time. The stems bear, at the end of long red petioles, alternate, elongated and pointed, leathery leaves, which can absorb atmospheric moisture. Flowering takes place from April to October. The inflorescences are large heads, carried at the terminal part of each branch. They measure 12 to 30 cm in diameter. Mature and well-established plants are capable of producing up to ten heads per season. The flower buds resemble magnificent artichokes with pearly scales. The head opens and the bright pink and velvety bracts unfold to a velvety, white to pink, powdery plateau. This flowering attracts many pollinating insects and gives way to some velvety seeds almost as large as walnuts. The thick roots of this protea also serve as a storage organ. In case of fire, it is capable of regenerating from its roots, nourished by its own ashes.

Protea cynaroides is a mythical plant that leaves no one indifferent. It will prefer to settle in coastal gardens spared by heavy frost, in light, slightly acidic soil. It is particularly suited to the Mediterranean climate and thrives in poor, dry to arid soils. It can be planted as a solitary specimen, on large slopes or in the background of flower beds, in a dry garden, but always in an open position, in full sun. In an exotic garden, it can be associated with the Pride of Madeira, Leucadendrons, and Melianthus major, for example.

Planting and care

The Protea has particular requirements in terms of substrate and cultivation. It does not like limestone, excess moisture, or fertiliser. This exotic plant needs a warm and sunny exposure, and very well-draining, rather acidic soil. To improve drainage, coarse sand can be added at the time of planting, possibly with a little gravel or pumice. This species tolerates rocky and rather dry soils. Young royal proteas must be protected from frost during their first years, then they will tolerate -5 °C in dry soil.
You can grow it in a pot if you live in a cool climate to allow you to overwinter it easily.

A Protea is best planted in full sun, it needs a warm and bright location. Ideally, it should receive at least 6 hours of direct sunlight per day. The soil should be poor in organic matter. Avoid rich and humus-bearing substrates, as well as heavy and clayey soils. Ideally, the pH should be between 5.5 and 6.5. We recommend adding a little ash or charcoal to the planting soil.
