Alternate, occasionally opposite, entire or lobed leaves each have 3 prominent veins. Large, long-stemmed, mostly solitary flowerheads are borne from late summer to autumn. T. rotundifolia, the most commonly grown species, lends height to a mixed or annual border, and provides long-lasting cut flowers.
