Large shrub or small tree
What it is
Helicteres isora is a large shrub or small tree of the mallow family, with grey bark and broad, rough, toothed leaves. Its brick-red flowers fade to a dull pale blue as they age. The fruit is its most striking feature: a hard pod twisted into a tight screw, which gives it the names screw tree and valampuri, meaning turning to the right. It grows wild in dry forests across India, South-East Asia and northern Australia.
What it's used for
- Its strong bark fibre has long been used for rope and sacking.
- The twisted pods are sold in herbal markets and used in Ayurveda and Siddha, where the bark, root and fruit are traditional remedies for stomach complaints such as diarrhoea.
- Its bright red flowers make it an attractive native shrub for gardens.
