Celmisia

This New Zealand cousin of the aster has the same golden centre and daisy-like white flowers, but it is also blessed with striking silver-green leaves that are slightly furry to the touch. The plant is found all over the country, but particularly in high, mountainous areas where it will cling to rocks and stony outcrops. It's extremely hardy and regularly survives snowy winters in Southern Alps of New Zealand. As an alpine plant, it needs well-draining soil with plenty of grit.
