Roque de los Muchachos (English: "Rock of the Boys") is a rocky mound at the highest point on the island of La Palma in the Canary Islands, Spain.
 The rocks are found at an elevation of 2,423 m above sea level, not far from the Observatorio del Roque de los Muchachos, where some of the world's largest telescopes are situated; the altitude and the dryness of the climate here give rise to excellent observing conditions.
 The rocks are contained with the Parque Nacional de la Caldera de Taburiente.
Echium wildpretii" subsp.
 "trichosiphon is an "Echium" that is found high up in the area of La Caldera de Taburiente on the Canary Island of La Palma.

 The plant is biennial and dies after flowering.
 This plant can be grown in gardens, but requires good drainage and fairly mild conditions.
 The plant hates water falling in the centre of the rosette and will often rot in such conditions.

 The expansion is part of efforts to improve the condition of the wetland, which has been damaged by over-exploitation of water resources.
