About New Zealand Everlasting Daisy

Helichrysum bellidioides · also called New Zealand Everlasting Daisy, Everlasting Daisy · flowering

Helichrysum bellidioides (syn. Anaphalioides bellidioides) is a mat-forming, evergreen alpine perennial endemic to New Zealand, where it carpets rocky outcrops, fell-fields, and open grassland from low to subalpine altitudes. It forms low mats of small, obovate leaves that are dark green above and white-felted beneath, with white-hairy stems bearing pure white, papery, daisy-like everlasting flowerheads in late spring and early summer. The key care requirement is sharply drained, gritty soil in full sun with protection from winter wet, making it ideal for rock gardens and alpine troughs. It is not listed by the ASPCA and is classified here as mildly-toxic on precautionary grounds.
