Icarian Treacle Mustard
erysimum scoparium
The Icarian Treacle Mustard, scientifically known as Erysimum scoparium, is a resilient and striking perennial subshrub endemic to the high-altitude volcanic regions of the Canary Islands, notably around Mount Teide in Tenerife. Thriving in harsh, windswept environments where few other plants can survive, this wallflower species has adapted beautifully to intense sunlight, poor volcanic soils, and dramatic temperature fluctuations. It forms dense, rounded, broom-like mounds that burst into color during the spring, offering vital resources to local high-altitude pollinators. Its presence adds a touch of vibrant life to the otherwise barren, extra-terrestrial-looking volcanic landscapes. Nature enthusiasts and hikers visiting the high peaks of the Canaries often admire this plant for its rugged survival skills and sweet-scented floral displays that transition from white to deep violet as they age.
Lebensraum: Found in dry, high-altitude volcanic scrublands and rocky slopes of the Canary Islands, particularly around Mount Teide.
Aussehen
Erysimum scoparium is a woody-based perennial shrub growing between 30 and 120 centimeters in height, characterized by its dense, upright, broom-like branching habit. It features narrow, linear, grey-green leaves that are covered in fine, pressed hairs, giving the foliage a silvery-matte appearance. The flowers are arranged in dense terminal racemes; each small flower has four petals that display a dramatic color gradient. Newly opened flowers start as a pale lilac, white, or yellow, gradually darkening to an intense violet or purple as they age and are pollinated, creating a multi-colored cluster effect on a single stalk.

The specific epithet 'scoparium' means broom-like in Latin, referring to its stiff, brushy branches.
This resilient plant can withstand temperatures below freezing during alpine winter nights as well as intense midday heat.
Besondere Fähigkeiten
Fähigkeit
Color Shifting Cues
The blossoms shift color from pale white to deep violet after pollination, signaling to visiting insects which flowers still contain nectar.
