Celmisia semicordata subsp. semicordata
Large Mountain Daisy
A superb, Agave-like perennial in the daisy and sunflower family (Asteraceae), native to a variety of habitats on the South Island of New Zealand. It forms an patch of rosettes with broad, silvery green leaves to 42 cm (17 in.) long that are strongly silvery-hairy below, and rise from an underground rootstock. The daisy-like flowers are held on stalks just above the leaves. In cultivation, it is easily grown and prefers a shaded position on moist but well drained, acidic soil in a temperate climate. It dislikes excessive heat and humidity. Seeds may benefit from cold stratification for up to 3 months.
