Species of flowering plant
Echium vulgare , known as viper's bugloss and blueweed ,[ 1] is a species of flowering plant in the borage family Boraginaceae . It is native to most of Europe and western and central Asia [ 2] [ 3] and it occurs as an introduced species in north-eastern North America , south-western South America and the South and North Island of New Zealand.[ 1] [ 4] The plant root was used in ancient times as a treatment for snake or viper bites .[ 5] If eaten, the plant is toxic to horses and cattle through the accumulation of pyrrolizidine alkaloids in the liver .[ 6] [ 7]
Description
It is a biennial or monocarpic perennial plant growing to 30–80 cm (12–31 in) tall, with rough, hairy, oblanceolate leaves .[ 8] The stems, which are red-flecked, resemble snake's skin and even the fruits are shaped like adders' heads.[ 9] The flowers start pink and turn vivid blue, and are 15–20 mm (0.59–0.79 in) in a branched spike, with all the stamens protruding. The pollen is blue[ 10] but the filaments of the stamens remain red, contrasting against the blue flowers. It flowers between May and September in the Northern Hemisphere . The Latin specific epithet vulgare means common.[ 5]
Distribution
It is native to Europe and temperate Asia. It has been introduced to Chile ,[ 11] New Zealand [ 12] and North America , where it is naturalised in parts of the continent including northern Michigan ,[ 3] being listed as an invasive species in Washington .[ 13] It is found in dry, calcareous grassland and heaths , bare and waste places, along railways and roadsides and on coastal cliffs , sand dunes and shingle .[ 14]
Cultivation
E. vulgare is cultivated as an ornamental plant, and numerous cultivars have been developed. The cultivar 'Blue Bedder' has gained the Royal Horticultural Society 's Award of Garden Merit .[ 15] [ 16]
