How to Grow Hesperantha

Hesperantha coccinea

Perennial

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.

Growing Tips

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.
