Description

Wild cottoneaster is a member of the rose family. It is a bushy deciduous shrub that grows to a height of 100 cm. In young shrubs, the stems are woolly, but they become smooth in older specimens. The leaves are green and matt on the upper surface but grey and woolly underneath. The small flowers have pink petals, and the berry-like fruits are red (2). Until quite recently it was thought to be a native endemic species, but its taxonomic status is currently in doubt. It is now believed that it may actually be the same species as the widespread C. integerrimus, and therefore an introduced plant (5).

Range

Just a few plants are found on Great Ormes’ Head in Caernarvon, north Wales. It has always been rare at this site, and in 1978 the population reached a low of just 6 plants. As a result of introducing cultivated plants this number was increased to around 33 plants (4).

Habitat

Found on limestone rocks and ledges (5).

Biology

This deciduous shrub does not seem to regenerate by seed or by vegetative reproduction at the site in Wales (5). The flowers are visited by a range of insects, including wasps (2).

Threats

Since it was discovered in 1825 this shrub has declined due to poor fruiting, scrub encroachment and grazing (5). Damage by climbers is also thought to have been a problem (4).

Deciduous: a plant that sheds its leaves at the end of the growing season.
Endemic: a species or taxonomic group that is only found in one particular country or geographic area.
Vegetative reproduction: type of asexual reproduction (reproduction without recombination of genetic material) that results in the propagation of plants using only the vegetative tissues such as leaves or stems. The resulting plant is genetically identical to the original plant. A well-known example of this is the reproduction of strawberry plants from ‘runners’.
