White-Flowered Broom
cytisus supranubius
The White-Flowered Broom, scientifically known as Cytisus supranubius, is an iconic subalpine shrub endemic to the high-altitude volcanic landscapes of the Canary Islands, most notably Mount Teide on Tenerife and the highlands of La Palma. Locally called 'Retama del Teide', this resilient plant plays a vital ecological role, forming dense scrub communities that stabilize the loose volcanic soil and provide shelter for local fauna. It is celebrated for its spectacular spring display, where it transforms the rugged, barren caldera into a sea of fragrant white and pink blossoms.
Hábitat: Found in high-altitude volcanic scrublands and subalpine zones, typically at elevations between 1,800 and 3,000 meters above sea level.
Aspecto
This highly branched, rounded shrub typically reaches heights of 1 to 3 meters. It is characterized by its stiff, upright, grey-green stems that appear largely leafless for most of the year, a specialized adaptation to reduce water loss. The leaves are small, narrow, and trifoliate, falling off early in the season. In late spring, it bursts into dense, terminal clusters of small, pea-like white or pale pink flowers that blanket the plant and emit a highly sweet, honey-like fragrance.

Datos interesantes
Beekeepers move their hives to the Teide caldera in spring to produce 'Miel de Retama' (Broom Honey), a highly prized, light-colored local honey.
The species name 'supranubius' translates directly to 'above the clouds', describing its high-altitude habitat.
When in full bloom, the sweet scent of thousands of these shrubs can be smelled from miles away across the volcanic plateau.
Habilidades especiales
Above the Clouds Photosynthesis
Utilizes its green, broom-like stems to perform photosynthesis when leaves are shed to conserve moisture in dry, high-altitude air.
Volcanic Soil Enrichment
Houses symbiotic Rhizobium bacteria in its root nodules, allowing it to fix atmospheric nitrogen and enrich nutrient-poor volcanic soils.
Extreme Alpine Resilience
Withstands intense solar radiation, extreme summer heat, drought, and freezing winter temperatures typical of alpine environments.
