Helichrysum petiolare is a shrub or vine that is not native to California.
[Cal-IPC] Invasive: Helichrysum petiolare (licorice plant) is 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. Licorice plant 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. Licorice plant has been growing outside of cultivation for several decades, but these naturalized populations do not appear to spread very rapidly.

[Wikipedia] South Africa native, Description: Helichrysum petiolare, the licorice plant  or liquorice plant, is a species of flowering plant in the family Asteraceae, native to South Africa ? where it is known as imphepho ? and naturalized in parts of Portugal and the United States. Growing to about 45 cm (18 in) high and 150 cm (59 in) broad, it is a trailing evergreen subshrub with furry greygreen leaves and small white flowers. Other common names include silver-bush everlastingflower, trailing dusty miller and kooigoed. The foliage has a faint licorice aroma, but Helichrysum petiolare is not closely related to the true liquorice plant, Glycyrrhiza glabra. (contributed by Mary Ann Machi)
