Echium wildpretii is a
Mount Teide in Tenerife. The subspecies E. wildpretii subsp. trichosiphon occurs at high altitudes on the island of La Palma. The common names are tower of jewels, red bugloss, Tenerife bugloss or Mount Teide bugloss.[1]
Etymology
The Latin specific epithet wildpretii honours the 19th century Swiss botanist Hermann Josef Wildpret.[2]
Description
It is a biennial, producing a dense rosette of leaves during the first year, flowers in the second year, and then dies. The red flowers are borne on an erect inflorescence, 1–3 m (3 ft 3 in – 9 ft 10 in). The plant blooms from late spring to early summer in Tenerife.
Habitat
The plant grows in the
Mount Teide, a volcano on Tenerife in the Canary Islands, Spain. It requires a lot of sun and is found in arid and dry conditions, but it tolerates frost down to −5 °C (23 °F). As a sub-alpine endemic plant with a narrow climatic niche and small distribution, the species is likely to be negatively impacted by climate change.[3][4]
Uses
This plant can be found as a garden ornamental but is intolerant of low temperatures, thus some winter protection is required in frost-prone areas. It has gained the Royal Horticultural Society's Award of Garden Merit.[5][6] As with most buglosses, it is favoured by bee-keepers for its high nectar content.
