About

Acalypha hispida, the chenille plant, is a flowering shrub which belongs to the family Euphorbiaceae, the subfamily Acalyphinae, and the genus Acalypha. Acalypha is the fourth largest genus of the family Euphorbiaceae, and contains many plants native to Oceania.

How to grow it

When grown as a house plant, it needs bright light but not direct sunlight, and requires high humidity and a temperature of at least 61 °F (16 °C). It should be grown in a loose potting soil, rich in organic matter and sand, and must be kept well-watered during the spring and summer. Watering should be reduced somewhat in fall and winter. It is typically propagated from cuttings.

Safety

The clear latex is poisonous and can irritate the skin and mucous membranes (signs of intoxication do not appear until massive amounts of plants have been absorbed). Roots, leaves and flowers are used for medical purposes. The plant itself is very resistant to diseases, but with a certain vulnerability to aphids, which can colonise it and bring it to death.
