Local CNPS members have located them in the Dunes as follows&#8211;1984: Hidden Willow Valley by Malcolm McLeod and Austin Grif\ufb01ths; 1986: Kathleen Jones; 1990: south of Oso Flaco Lake by Lynne Dee Althouse and David Keil. Germinating following rainfall, leaves have blades which are deeply cut (pinnately lobed), into several toothed lobes and are sticky to the touch. The spectacular fuchsia colored, daisy-like in\ufb02orescence bears \ufb02ower heads lined with black-tipped phyllaries (leaf-like plant part located just below a \ufb02ower). They contain many (100+) deep yellowish disc \ufb02orets at the center. Each has 13+ fuchsia colored ray \ufb02orets. The \ufb02ower heads turn into \ufb02uffy white seeds, ready for the wind to disperse the seeds. <em>Senecio elegans<\/em> is an escaped invasive weed where it spreads rapidly, displacing indigenous vegetation such as Dunedelion (<em>Malacothrix incana<\/em>). Control is achieved by pulling it before \ufb02owering. I\u2019ve been able to easily pull many hundreds in the Dunes south of Oso Flaco.<\/p>\n<p>Mark Skinner: Invasive Species Chair<\/p>\n<p>Photo: Mark Skinner<\/p>\n","protected":false},"excerpt":{"rendered":"<p>An attractive member of the Asteraceae (Sun\ufb02ower) family Senecio elegans is an erect annual herb, up to 1 ft. tall and to 1.5 ft. wide.
