Common names: licorice plant

Helichrysum petiolare (licoriceplant) is a shrub (family Asteraceae) found in forested areas and coastal scrub on the central coast, including the southern side of Mt. Tamalpais and the Monterey Peninsula. Licoriceplant is a landscape ornamental that has escaped cultivation, invading undisturbed habitats. It reproduces by seed and vegetatively from stem fragments.
The extent of its impacts are unknown, but it can grow to form dense stands that may crowd out native plants. Licoriceplant has been growing outside of cultivation for several decades, but these naturalized populations do not appear to spread very rapidly.
