Contents

Naming

Hemigraphis alternata was already described and the name validly published by Nicolaas Laurens Burman. It was Thomas Anderson, however, who reclassified it into todays valid botanical systematics in 1863.

Taxonomy

Hemigraphis alternata is a species in the genus Hemigraphis which contains approximately 20 to 83 species and belongs to the family of the Acanthaceae (Acanthus Family).

Characteristics

The perennials reach heights of 5 to 15 centimetres. The plants reach a width of 30 to 60 centimetres.

Leaves

Hemigraphis alternata is evergreen. The yellow-green, simple leaves are opposite. They are ovate with crenate margins. The surface of the leaves is leathery.

Flowers and Fruits

Hemigraphis alternata produces spikes of white tubular flowers from April to July. The plants are hermaphroditic.

The perennials produce loculicidal capsules.

Root System

Distribution

The origin of Hemigraphis alternata is uncertain.

Cultivation

The perennials prefer a half-shady situation on fresh to moist soil. The substrate should be sandy-loamy, gritty-loamy or sandy clay soil. They tolerate temperatures only above at least 1°C (USDA zone 10).

Uses

Suited for hanging baskets, as well as suited as indoor plant. Hemigraphis alternata can be used in the foreground of aquariums with water temperatures of 18 to 28°C. The water should be soft to hard, the pH-value should be between 6 to 8.

Maintenance and Propagation

Pests and Diseases

Honeydew, galls and distorted leaves are a sign for an infestation with aphids. Use an insecticide or control biologically , e.g. with parasitic wasps or predators such as Aphidoletes aphidimyza.

Fine webs on the plants indicate an infestation with red spider mites. These sap-sucking insects mainly appear under glass and can be controlled either with insecticide or biologically with parasitic mites.
