Introducing the Aloe black gem, known as Alworthia Black Gem. It's a really cool succulent plant that's become quite popular among plant enthusiasts. Alworthia 'Black Gem' is an interspecific hybrid created by crossing Aloe speciosa and Haworthia cymbiformis. It is also known as Alworthia pentagona

Aloe 'Black Gem' is an appreciated succulent that grows thick, fleshy, triangular leaves in stemless rosettes. It spreads freely, making a dense clump. In direct sunlight, the leaves change color from dark green to reddish-brown or bronze. The more sun they receive, the darker and redder they get. These leaves have white spots or tubercles on their upper surfaces, giving them an interesting textured appearance. It's a small to medium-sized succulent that can reach a mature size of about 6 to 8 inches in height.

When it comes to flowers, the Black Gem Aloe produces small tubular flowers that can vary in color from pale pink to coral. The flowers typically bloom in the summer months and can add a lovely touch to the plant's overall aesthetic.

In terms of care, the Alworthia Black Gem prefers bright but indirect sunlight. It's important to avoid exposing it to direct sunlight for extended periods as it can lead to leaf burn. As for watering, it's best to let the soil dry out completely between waterings to prevent overwatering, which can cause root rot. Use well drained succulent potting mix for healthy growth. If growing indoors, your Aloe black gem thrives in warm temperatures between 65-75 °F. For outdoor cultivation, it is well-suited in USDA zones 9-11.

Propagation of the Black Gem Aloe can be done through offsets or leaf cuttings. Offsets are small baby plants that grow from the base of the mother plant and can be separated and potted individually. Leaf cuttings involve taking a healthy leaf and allowing it to callus over before planting it in well-draining soil.

Overall, the Alworthia Black Gem is a stunning succulent with its dark foliage and unique triangular leaves. It's relatively low maintenance, making it a great choice for both beginner and experienced plant lovers.
