GENUS INDEX

GENUS CODE: PACKE
GENUS SCIENTIFIC: Packera
GENUS AUTHORITY: Á. Löve
GENUS COMMON: Ragwort
GENUS SUMMARY: A genus of about 65 species, annual and perennial herbs, of subtropical, temperate, and arctic North American, with a few species in Siberia. These species have usually been considered part of Senecio, and have often been given informal status as the Aureoid group. According to recent interpretations, this group warrants generic status, as Packera (Bremer 1994).

HORTICULTURAL
Plant Sale Text: Small’s ragwort closely resembles its relative golden ragwort with its bright yellow cluster of flowers and persistent rosette of green leaves. However, unlike its relative, Small’s ragwort thrives in dry, poor soils and is often found on sunny roadsides. Also, the leaves of Small’s ragwort are deeply dissected, making it visibly distinct from the round, un-lobed leaves of golden ragwort. Although Small’s ragwort does not spread vegetatively, it will readily self-sow in appropriate conditions.
