Long known as Aster natalensis, this South African daisy is a classy, showy alpine. The large flowers are a good, mid-blue with contrasting yellow eyes and carried singly on top of 12cm stems in early summer. The mats of long green leaves are fairly evergreen.
Enjoys full sunshine and well-drained soil (but not too dry and parched in summer). The flowers have a curious feature - they open wide in sunshine but when the sun goes down the petals recurve backwards (towards the stem), not closing like most flowers.
