Description

S. saxorum is a small herbaceous plant that forms mounds of about 5-8 cm high. This semi-shrubby stemmed species falls under the subgenus Streptocarpella and the foliage is quite different to the more common Streptocarpus. Its slender, hairy stems spread along the ground crowded with small, matt-green, softly hairy, fleshy, elliptic to ovate leaves that occur in whorls of three. Its branches become slightly woody with age. The young growth is quite flexible and will naturally trail from a suspended container/pot.

 

Streptocarpus saxorum flower

 

The single or paired tubular flowers occur on slender stalks, arising from the upper leaf axils. They are very attractive with a white tube contrasting with lilac-mauve, violet-like lobes. The three lower petal lobes are larger than the upper two. The flowers are small in size, but are produced continuously throughout the spring and summer months, even into winter when growing conditions are favourable.

 

The slender twisted seed pods are velvety when unripe, and as they dehisce they twist open longitudinally releasing many small fine seeds.

 

 

 

This plant is relatively fast growing as it takes one year for a young seedling to grow to flowering size.

 

 

Distribution and habitat

This plant occurs in Kenya and Tanzania. It is found on rocks and cliff faces which are often exposed to the sun.

 

Derivation of name and historical aspects

Streptocarpus derives from the Greek streptos, twisted, and karpos, a fruit. The species name 'saxorum' is a reference to it occurring amongst rocks.

 

S. saxorum was first described in 1983 from material found on rocks by C. Holst.
