Phenology | Flowering summer. | Flowering mostly spring–summer (sparingly at other times). |
Habitat | Talus slopes | Disturbed coastal sites |
Elevation | 3000–3700 m (9800–12100 ft) | 0–100 m (0–300 ft) |
Distribution |
CA; NV |
CA; Africa [Introduced in North America] |
Discussion | Of conservation concern. Senecio pattersonensis has the aspect of a depauperate S. fremontii with notably narrow leaves. Some plants in collections appear to be intergrades with S. spartioides. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Senecio elegans escapes from cultivation and persists along the central coast of California. Native to South Africa, it is now established widely in areas of Mediterranean climate. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
