Appearance
"Erysimum scoparium" is a small shrubby perennial plant. It has stiff, linear to slightly pointed leaves. The flowers are arranged on upright stems. They darken to a purplish colour as they mature. The seed pods are held more or less erect and have brown seeds. A subspecies, "E. scoparium" subsp. "cinereum" has been distinguished by its more erect habit and longer inflorescences. Plants from Gran Canaria have broader leaves and dark brown rather than yellowish brown seeds, and have been separated as "E. albescens" by some sources.Distribution
"Erysimum scoparium" is endemic to the Canary Islands. It is found in montane zones in Tenerife, up to altitudes of 1600–2200 m in Las Cañadas, and 300–500 m in the Valle del Santiado del Teide. It is also found in mountainous regions of La Palma. When "E. albescens" is included in "E. scoparium", the latter's distribution extends to Gran Canaria, where it is found in dry habitats and pine forest at elevations of 1400–1800 m.References:
