So let’s dive into the world of Amorphophallus atroviridis!

Characteristics of Amorphophallus atroviridis

Amorphophallus atroviridis is a species of amorphophallus that originates from the rocky cliffs in north central Thailand near Sara Buri. This plant thrives in crevices among limestone boulders, and its tuber grows deep due to its natural habitat. In cultivation, it is essential to use tall pots to accommodate the deep growth of the tuber.

The leaves of Amorphophallus atroviridis are dark green, almost emerald-blackish in color, which sets it apart from other species in the same genus. The leaves have a striking pink margin, adding to the plant’s ornamental appeal. When new leaves emerge, they are deep purple-red but gradually change to the dark green color as they mature. The stalks of the plant are reddish-brown and often speckled.

Amorphophallus atroviridis produces an inflorescence around June or July. The inflorescence consists of a creamy-white spathe and a long yellowish spadix. Although the flowers are impressive, it’s important to note that they are short-lived. However, the plant’s bold foliage makes it an attractive choice even without the presence of flowers.

Care Instructions for Amorphophallus atroviridis

Light and Temperature Requirements

Amorphophallus atroviridis thrives in bright to medium indirect sunlight. It is important to avoid direct exposure to intense sunlight, as it can scorch the leaves. In terms of temperature, this plant prefers a range of 18°C-30°C (64°F-86°F), with temperatures not dropping below 15°C (59°F). It is best to keep the plant in a warm and well-lit location, away from drafts and cold air.

Watering and Humidity

When it comes to watering, it’s crucial to strike the right balance. Amorphophallus atroviridis prefers to dry out slightly between waterings, so it’s advisable to allow the potting mix to dry about 3.5cm (1.4 inches) down before watering again. During warmer months, when the plant is actively growing, watering should be more frequent. However, during the plant’s dormancy period, which usually occurs during the winter months, minimal watering is required to prevent tuber rot.

Maintaining average humidity levels is ideal for Amorphophallus atroviridis. If the air in your home is dry, you can increase humidity around the plant by placing a water-filled saucer or tray with pebbles underneath the pot. This creates a humid microclimate around the plant, supporting its growth and health.

Soil and Fertilizer

Amorphophallus atroviridis thrives in a well-draining potting mix. It is recommended to use an Aroid mix specifically tailored for aroids and their unique needs. This type of mix ensures proper drainage while retaining enough moisture for the plant’s roots. You can also add perlite or orchid bark to increase the drainage capacity of the soil.

Fertilizing the plant during the growing season can promote healthy growth. A balanced, water-soluble fertilizer with an NPK ratio of 20-20-20 or a similar formulation is suitable for Amorphophallus atroviridis. Follow the manufacturer’s instructions for proper dilution and frequency of application.


It is essential to note that Amorphophallus atroviridis is toxic to humans and animals when ingested. Keep this plant out of reach from children and pets to ensure their safety.

Propagation of Amorphophallus atroviridis

Propagation of Amorphophallus atroviridis can be done through various methods, although specific information regarding its propagation is limited. However, we can draw insights from successful propagation methods employed for other Amorphophallus species.

Leaf cuttings, petiole cuttings, and tuber cuttings are common propagation methods used for Amorphophallus. Leaf cuttings involve taking cuttings of healthy leaves and patiently nurturing them until they develop roots and form new plants. Petiole cuttings require partially cutting the petiole and placing it on damp milled sphagnum moss or a similar medium. Tuber cuttings involve dividing the tubers into sections and planting them separately.

It’s important to note that propagation may require patience and experimentation to achieve successful results. The success rates and effectiveness of these propagation methods for Amorphophallus atroviridis specifically may vary, so it’s advisable to consult experts or experienced growers for more detailed instructions.
