Poisonous (Connor 1977).
Tree tobacco is occasionally cultivated in milder parts of the country and is very distinct from any other sp. in N.Z. because it is an almost glabrous, glaucous-leaved shrub (often a small tree in warmer countries), and has yellow tubular fls with very small lobes (Fig. 114).
