Serruria phylicoides aka Bearded Spiderhead

Taxonomy ID: 3798

Serruria phylicoides, commonly known as Bearded Spiderhead or Downy Spiderhead (Afrikaans: Donsigespinnekopbos), is a flowering shrub in the family Proteaceae, within the large and diverse genus Serruria. The species was first described as Leucadendron phylicoides by P.J. Bergius in 1766, and formally transferred to Serruria by Robert Brown in 1810. It has accumulated numerous synonyms over the centuries, including Serruria barbigera Knight, Serruria arenaria R.Br., and Protea abrotanifolia Andrews, reflecting early botanical confusion within the genus.

The plant reaches approximately 1 metre in height and is a characteristic component of the fynbos biome — the extraordinarily species-rich shrubland unique to South Africa's Western Cape. Its native range is restricted to a few mountain ranges in the Western Cape: the Du Toits Peak area, the Hottentots Holland Mountains, the Riviersonderend Mountains, and the Kleinrivier Mountains. This narrow endemism places it firmly as a South African botanical treasure, not found anywhere else in the world.

Flowering occurs from August through November, coinciding with the southern hemisphere spring season. Like many Proteaceae, the flowers are grouped in characteristic spiderhead-like inflorescences, a trait shared across the genus and referenced in its common names. The IUCN Red List assessed the species as Least Concern as of 2020, indicating that while its range is limited, current population levels do not meet the thresholds for a threatened status.

As a fynbos shrub, Serruria phylicoides is adapted to the Mediterranean-climate conditions of the Cape Floristic Region: warm dry summers, cool wet winters, nutrient-poor acidic soils, and a fire-driven ecology. These conditions are notoriously difficult to replicate in cultivation outside its native region, and the species is not suited to life as a houseplant.

More information about Bearded Spiderhead

Where does Bearded Spiderhead come from?

Serruria phylicoides is endemic to the Western Cape province of South Africa, occurring naturally in the Hottentots Holland Mountains, Du Toits Peak area, Riviersonderend Mountains, and Kleinrivier Mountains. It is a member of the fynbos biome, one of the world's six floral kingdoms and the most species-rich per unit area. It is not native to any other region and has not been recorded as naturalised elsewhere.

When does Bearded Spiderhead flower?

🌸 August to November

The flowering season of Serruria phylicoides runs from August through November — southern hemisphere spring. The genus name Serruria and common names such as "Bearded Spiderhead" and "Raspberry Burst" refer to the distinctive pin-cushion or spiderhead-like inflorescences typical of the genus. The plant is a shrub growing to roughly 1 metre, producing its flowers within the fynbos understorey of the Western Cape mountains.

What are the common names and varieties of Bearded Spiderhead?

Serruria phylicoides is known under several English common names: Bearded Spiderhead (preferred), Downy Spiderhead, Raspberry Burst, Silky Spiderhead, and Bearded Serruria. In Afrikaans it is called Donsigespinnekopbos; in Chinese, 鬚葉新娘花. Taxonomic synonyms that have appeared in historical literature include Serruria barbigera Knight, Serruria gracilis Knight, Serruria arenaria R.Br., and Protea abrotanifolia Andrews, among many others, reflecting complex early classification within the Proteaceae.

How big does Bearded Spiderhead grow?

Serruria phylicoides grows as a shrub reaching approximately 1 metre in height. As a fynbos species adapted to fire-prone, nutrient-poor soils of the Western Cape mountains, it generally forms a compact, multi-stemmed shrub. No reliable data on typical spread is available in current horticultural references.

Can Bearded Spiderhead be grown outdoors?

Serruria phylicoides is a South African fynbos endemic adapted to the Mediterranean-type climate of the Western Cape: warm dry summers, cool wet winters, low-nutrient acidic soils, and periodic fire. These conditions are difficult to replicate outside South Africa. The species is not suited to general houseplant cultivation and would require outdoor conditions mimicking its native fynbos habitat to thrive.

What are the water needs for Bearded Spiderhead

Bearded Spiderhead should be watered regularly, allowing the soil to dry out between waterings.

What is the sunlight requirement for Bearded Spiderhead

Bearded Spiderhead thrives in bright and direct sunlight. To ensure your plant receives enough light to survive, place it less than one foot from a window. The current weather in your area may affect the placement in your home. For example, if you live in a region that has longer and more intense periods of sunlight, then you may want to place the plant farther away from the window to avoid direct sunlight and reduce the risk of sunburn. Alternatively, if you live in a region with relatively milder temperatures and less intense sunlight, then you may be able to place the plant closer to the window for increased exposure. Ultimately, the current weather in your area should be taken into consideration when determining the best placement for your Protea Cyanoides.

Is Bearded Spiderhead toxic to humans/pets?

The toxicity level of this plant has not been officially confirmed by Ploi. If there is a possibility of ingestion of plant material with an uncertain toxicity by you, a family member, or a pet, it is advisable to seek the assistance of a medical professional.
