Black Spined Aloe Aloe melanacantha
ABOUT
Aloe melanacantha, commonly known as the Gorilla's Paw Aloe, is a distinctive succulent that boasts a unique and striking appearance. It's characterized by its rosette of thick, fleshy leaves which have a striking coloration and texture. Each leaf is adorned with white speckles and pronounced dark spines along the margins and the surface, giving the impression of a gorilla's knobby fingers - a feature from which it gets its common name. The leaves themselves have a green to bluish-green hue that contrasts sharply with the dark, almost black thorns. These thorns are one of the plant's most notable characteristics, providing both an element of drama and a defensive mechanism against herbivores. Toward the base, the leaves may take on a more pronounced curve, further adding to the sculptural quality of the plant. During the blooming season, the Gorilla's Paw Aloe produces flowers that add to its visual interest, but the description is focused on the plant's foliage and distinctive physical features. Its overall appearance is one of rugged beauty, with a strong and resilient nature that is reflected in its sharp spines and tough, drought-resistant leaves.

ToxicityTo humans
Aloe melanacantha, commonly known as Aloe, is not typically known for being highly toxic to humans. However, like many other Aloe species, it contains aloin in its sap, a compound that can cause gastrointestinal irritation if ingested. The symptoms from ingesting Aloe may include diarrhea, abdominal cramps, and possibly red urine due to the presence of anthraquinones. It is important to note that topical application is generally considered safe, but any ingestion of the plant, particularly in larger quantities, should be avoided due to these potential adverse effects.
To pets
Aloe melanacantha, commonly referred to as Aloe, can be toxic to pets if ingested. The toxic compounds, such as saponins and anthraquinones found in Aloe, can cause vomiting, diarrhea, lethargy, changes in urine color, and, in severe cases, may lead to tremors or rarely, more severe symptoms. It is advisable to keep Aloe away from pets and to consult a veterinarian immediately if you suspect your pet has ingested any part of the plant.

WaterAloe melanacantha, commonly known as Dwarf Aloe, should be watered deeply but infrequently. Allow the soil to dry out completely before watering again, which typically means watering every two to three weeks depending on the climate and indoor conditions. When you do water, provide enough water so that it runs out of the drainage holes—this might be around 16 ounces for a small pot. Reduce watering during the winter months, as the plant enters a dormant period and uses less water. Overwatering can lead to root rot, so it's crucial to err on the side of underwatering rather than giving too much.
LightFor optimal growth, Dwarf Aloe requires bright but indirect sunlight. Position it in a spot that receives plenty of natural light throughout the day without being exposed to harsh midday sun, which can scorch the leaves. An east-facing or north-facing window is ideal, or a south-facing window with some light-diffusing curtains. Artificial grow lights can be used if there is not enough natural sunlight available.
TemperatureDwarf Aloe thrives in temperatures between 60 and 75 degrees Fahrenheit, but it can survive temporary dips down to about 50 degrees and as high as 85 degrees Fahrenheit. Keep the plant away from drafts and cold windows in the winter, and avoid exposing it to temperatures below 50 degrees, as this can damage the plant. The ideal temperature range for growth ensures that the Dwarf Aloe is comfortable and stress-free.
PruningPruning Dwarf Aloe is primarily done to remove any damaged or dried-out leaves to maintain the plant's appearance and health. Use clean, sharp shears and cut as close to the base of the leaf as possible without damaging the main stem. Pruning is best done in the spring or early summer when the plant is actively growing, although damaged leaves can be removed as needed throughout the year. Generally, Dwarf Aloe requires minimal pruning.
CleaningAs needed
SoilThe best soil mix for Aloe melanacantha, commonly known as black-spined aloe, is a well-draining cactus or succulent mix with added perlite or pumice to increase drainage. The ideal pH should be between 6.0 to 8.0—but leaning towards slightly alkaline conditions is preferable.
RepottingBlack-spined aloe should be repotted every two to three years or when the current pot is clearly too small for its size. It's important to allow the soil to dry out completely between repottings.
Humidity & MistingBlack-spined aloe thrives in dry conditions and does not require high humidity. It prefers indoor household humidity levels, which typically range from 40% to 60%.
Suitable locationsIndoor
Grow in bright, indirect light, and allow soil to dry between waterings.
Outdoor
Needs full sun to partial shade and well-drained soil.

Life cycleAloe melanacantha, commonly known as Gwarri Aloe, begins its life as a seed, which germinates in well-drained soil with ample sunlight. After germination, the seedling emerges, developing fleshy leaves with characteristic spines and a rosette growth pattern. As the plant matures, it establishes a strong root system and grows larger, conserving water within its succulent leaves to survive in arid environments. This Aloe usually remains solitary but can produce offsets, leading to a clonal colony formation. The adult plant periodically produces a floral spike with tubular, red to yellow flowers, attracting pollinators and leading to the production of seeds. Concluding its life cycle, the Aloe dies after blooming and setting seeds, which then have the potential to germinate and start a new generation.
PropogationPropogation time
Spring-early summer
The most popular method of propagating Aloe melanacantha, commonly known as the Gorilla's Paw, is through offshoots or pups that grow from the base of the mature plant. These pups can be carefully removed when they have developed their own roots and are a few inches tall. The ideal time to do this is in the spring or early summer, which gives the young plants ample time to establish themselves during the growing season. Once removed, allow the pups' cut surfaces to dry and callus over for a day or two to prevent rotting. Then, plant the pups in well-draining soil, water sparingly at first, and gradually increase to give the young aloes a chance to acclimate and grow strong root systems.
