How to Grow Hesperantha
Hesperantha coccinea
Hesperantha is a gem for late-season colour, producing elegant crimson star-shaped flowers from September well into November. It thrives in moist but well-drained soil in sun or light shade and forms spreading clumps of grassy foliage. Plant corms 20cm apart in spring and keep soil consistently moist during the growing season. Mulch the crown in autumn in cold areas. Divide congested clumps every 3-4 years in spring to maintain flowering vigour.

Keep soil moist in summer
Unlike many perennials, hesperantha needs consistent moisture through summer to build energy for its autumn display. Do not let it dry out completely.
Late flowers extend the season
Hesperantha flowers when almost everything else has finished. Plant near asters and grasses for a stunning late border that peaks in October.
Divide regularly for best flowering
Clumps become congested after 3-4 years and flowering declines. Lift and divide in spring, replanting the healthiest outer portions.
Mulch for winter protection
In cold or exposed gardens, apply a thick mulch of bark or straw over the crown in late autumn after foliage dies back. Remove in early spring.
