Berzelia stokoei (E.Phillips) A.V.Hall
Common names: red kolkol (Eng.); rooistompie (Afr.)
The striking red flowers of Berzelia stokoei are a sight to behold when walking in the tranquil mountains of the Overberg region. This plant was previously called Brunia stokoei.
Berzelia stokoei is an upright, resprouting shrub, which grows to a height of 2 m. It has a similar growth habit to B. albiflora. However, the needle-like leaves are glabrous (smooth), stalkless, 8-10 mm long and have an evident midvein underneath.
The red flowers are borne in flower heads of 15 mm across during summer, from November to April.
Distribution and habitat
Berzelia stokoei occurs from the Hottentots Holland Mountains to Kleinmond, but is prevalent in the rocky sandstone mid slopes of the Betty's Bay and Kleinmond areas and is endemic to the Western Cape.
Derivation of name and historical aspects
The genus Brunia was named after Dr Cornelius Brun, who was a chemist and plant collector and Carl Linnaeus' contemporary. The species stokoei is named after a very important collector of fynbos plants, Thomas Pearson Stokoe who died at the age of 91.
TheTrichostetha fascicularis green protea beetle and sunbirds are known to frequent this plant when in flower.
Due to its striking red flowers, Berzelia stokoei is used in the cut-flower industry, but not as much as B. albiflora.
Growing Berzelia stokoei
Berzelia stokoei can be grown from seed as well as vegetatively (cuttings). Brunia stokoei is serotinous, the seed heads stay on the parent plant for more than one season and can withstand fires; because of this it is best to collect seeds from flower heads that are at least 2-3 years (seasons) old.
For best germination results treat seeds with the Kirstenbosch Instant Smoke Plus Seed Primer. Sow seeds in a well-drained acidic medium and cover with a thin layer of soil. Feed seedlings with Kelpak, a seaweed-based fertilizer, to strengthen the roots.
Take cuttings from healthy, actively growing shoots. Dip the cuttings in a rooting hormone and place into a rooting medium suited for fynbos plants. Cuttings can be placed on heating benches or in a warm, well-ventilated space. This will improve rooting. Keep the cuttings moist and do not allow them to dry out. Once rooted, plant into individual plant bags or pots and feed with an organic fertilizer. Keep plants in a well-ventilated area but out of direct sunlight until they have acclimatized to the environment.
