Chusquea culeou, the Chilean bamboo, [1] (Spanish : caña coligüe or colihue) is a species of flowering plant in the grass family Poaceae. An evergreen bamboo native to South America, unlike most species within the genus Chusquea , it is frost-tolerant and thus widely cultivated in temperate regions.

Distribution

It is native to the Valdivian rainforests, humid temperate forests of Chile and southwestern Argentina. Chusquea culeou is a keystone species which can control patterns of forest dynamics by impeding regeneration of tree species. [2]

Description

Growing to 8 m (26 ft) tall by 1.5 m (4.9 ft) broad, Chusquea culeou forms a substantial clump of greenery. It has hairy lanceolate leaves with a spine on their end, and its flower is a whisk of light brown colour. The plant also produces a caryopsis fruit. Blooming occurs after variable periods, that could last 60 years. After blooming and releasing its seeds, the plant dies. The cane is straight, up to 6 m (20 ft) in height, and was used by the Aboriginals for the pole of their spears. They are still used by the Mapuche people for a musical instrument known as trutruca .

A feature of this Chusquea is that the stems are solid, unlike most bamboos.

Cultivation

Chusquea culeou is cultivated as an ornamental plant in gardens.

This plant has gained the Royal Horticultural Society’s Award of Garden Merit [1] (confirmed 2017). [3]

<i>Jovellana</i> Genus of flowering plants

Jovellana is a genus of flowering plants in the family Calceolariaceae. It was formerly included in Scrophulariaceae, and is still listed by some authorities as belonging there. However, recent molecular research indicates that the family Scrophulariaceae was polyphyletic, meaning that it contained more than one lineage with different parents. So several of its genera - including Jovellana - have been split off and assigned to new or existing families.
