This is an undemanding small shrub about 1m tall, which has two good characteristics: it flowers in late autumn and winter, and it can grow in part shade. It is sometimes called linum or yellow flax, and is found over a wide region including South-West China and South-East Asia. It has pretty rounded flowers in a cheerful golden yellow hue, and these appear in May, June and July in Sydney gardens. It likes a reasonable soil but is not very fussy. It should be protected from frost in very cold gardens.
It should be cut back hard at the end of winter to keep it compact. It tends to sucker a bit but is not rampageous in my garden thus far. It is attractive grown nearby a yellow-variegated shrub such as Euonymus japonica 'Aureus', or with other bright winter flowers such as Justicia rizzinii or Abutilon.
