Brachyglottis lagopus, Mountain daisy, or Yellow rock daisy is a small flowering rosette herbaceous perennial native to New Zealand. It is found in the North Island from Taupo south and to South Canterbury or North Otago in the South Island, from coastal to low alpine area from near sea-level to 1500m asl, in open scrub, snow tussock, herbfields, rock crevices and grasslands. It prefers moist humus-rich soil perhaps a little gritty, in damp shady areas but will often succeed when self-sown into rock crevices. It is a variable species, with green leaves that can be hairy, and can vary in shape and size (often as big as 20 x 15cm) depending on the area. In older plants, the hairs become sparse on the top surface but the under surface is always covered in woolly tomentum. Its flowers are yellow and appear throughout the year (from September to June, but mostly December to April) on stalks that are up to 35cm high, followed by fluffy seed heads for wind dispersal.
