Iresine herbstii

Botanical Name: Iresine herbstii

Bright red leaves with prominent red veins are the attraction of this Brazilian plant. Luckily for us, it also happens to adapt well to being indoors, making it a spectacular room accent.

This tropical native needs warmth, humidity and plenty of light to thrive. Put it near a window or in a sunroom to maintain its vibrant color. If you set it on your porch or patio for the summer, keep it shaded from hot, direct sunlight.

Repot in spring. When you see roots growing out of the drainage holes, it is time to repot. Move it up to a container just 1-2 inches larger, using a pot with drainage holes to prevent soggy soil.

Prune it back. Pinch off soft stem tips to keep Iresine herbstii compact. Don't toss out those cuttings! Pot them up to grow more plants.

Watch for aphids. These tiny pests are attracted to the soft, new growth on the plant. Treat any infestation immediately.
