About the genus

Hesperantha is a genus of cormous flowering plants in the family Iridaceae. The genus name is derived from the Greek words hesperos, meaning "evening", and anthos, meaning "flower".

In the garden

Schizostylis coccinea 'Rosalie' is a perennial member of the Iridaceae from Southern Africa and Zimbabwe, reaching roughly 0.6 metres. It carries slim, upright foliage topped by erect flowering spikes that appear from late summer into autumn, extending the season when many summer perennials are past their best. Plant it in a spot that receives full sun or partial shade and offers a degree of shelter from strong winds; exposure matters because the flower spikes sit above narrow leaves. Soil should be moist yet well drained — this cultivar will not perform in either drought-prone dry soil or in permanently waterlogged ground. In UK terms it is H5, hardy in most gardens, but benefits from a sheltered aspect and consistent moisture through the growing season. Use Schizostylis coccinea 'Rosalie' at the back of a mixed border for late-season colour, in a deep container kept consistently moist, or on the margins of water features where the soil remains damp but drains. The upright spikes are useful where you want vertical late-summer and autumn colour without much height, and they sit distinctly above the foliage when in flower.
