Parietaria judaica is a perennial herb that is not native to California.
[Wikipedia] Etymology, Distribution, Allergy, Native of Europe, Asia and Africa: Parietaria judaica, with common names spreading pellitory or pellitory of the wall, is a species of herbaceous perennial plant in the family Urticaceae. The plant's pollen is highly allergenic.[2] In Australia it is also known as asthma weed, due to the high incidence of allergy.[3] It is unrelated to the herb pellitory (Anacyclus pyrethrum). It is easily confused with the very similar species Parietaria officinalis.[4]
