Calif., s Africa (Cape region), introduced in Europe.

Discussion

The species is included among the invasive species of California (C. C. Bossard et al. 2000); it is native to the Cape region of South Africa, long cultivated in Europe, and now widely offered for sale on the internet. In contrast to the assessment of invasiveness in California, one commercial website selling the species notes this “forms tangled mounds of trailing grey-felted leaves. Given something to scramble up, it will climb. And although this description makes it sound fairly rampant, it is definitely not invasive.” It is often recommended for planters and hanging baskets, where the silvery leaves provide backdrop for bright colors.

The name Helichrysum petiolatum D. Don has been misapplied to plants of H. petiolare.
