| Echium wildpretii | |
Red tajinaste (Echium wildpretii) is a species of flowering plant in the family Boraginaceae. It is an herbaceous biennial plant that grows up to 3 m (10 ft) in height. The species is endemic to the Canary Islands, and is found mainly in the national park surrounding Mount Teide in Tenerife. A similar species, the pink tajinaste, occurs at high altitudes on the island of La Palma. Other common names are tower of jewels, red bugloss, Tenerife bugloss or Mount Teide bugloss.[1]
Etymology
[edit]The Latin specific epithet wildpretii honours the 19th-century Swiss botanist Hermann Josef Wildpret.[2]
Description
[edit]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
[edit]The plant grows in the subalpine zone of the ravines of 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]
Inbreeding depression
[edit]Under conditions where water availability was normal there was no indication of inbreeding depression measured as seedling survival.[5] However, when the seedlings were subject to drought stress conditions, inbreeding depression was high (survival about 50.2%).[5]
Uses
[edit]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.[6][7] As with most buglosses, it is valued by bee-keepers for its high nectar content.
