설명

This is a charming Streptocarpus with dainty lilac flowers. It is both pretty and tough with succulent foliage which droops, making it ideal for hanging baskets and tall pots.

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.

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.

Conservation Status

None.

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.

 

Streptocarpus belongs to the same family, Gesneriaceae, as do the well known African violets and gloxinias that are grown as pot plants all over the world. This is a large family of mostly tropical and sub-tropical herbs, with ±130 genera, and ± 2900 species worldwide. There are 8 genera in Africa, with the one genus, Streptocarpus, in South Africa and it has ±51 species. The family is named after Konrad Gesner, a Swiss scholar. In 1963, 30 years after his death, his name was given to this family.

 

Streptocarpus is a genus of evergreen perennials, monocarps and annuals which can be grouped into three distinct growth forms:

1.stemless clump forming rosettes

2.unifoliates (plants with a single leaf)

3.soft shrubby stemmed plants

Their habitat varies greatly from forests, sometimes as epiphytes, and on damp bank or rocks in grasslands. They are sometimes referred to as Cape primroses.

 

Gesneriaceae are often epiphytic (growing on trees) or lithophytic (growing on rocks). The very small seed is wind distributed.
