Haworthia Coarctata (Haworthia coarctata, Haworthiopsis coarctata) is a flowering succulent plant native to South Africa's Eastern Cape Province that has become naturalized in Mexico. It's a succulent that grows in clumps of stems with fleshy, dark green to brownish-green leaves with white rounded tubercles. Its leaves are arranged in elongated rosettes, concealing an 8-inch-long stem. They can grow to be up to 2.8 inches long and 0.8 inches wide. From late spring to fall, the mature rosettes produce slender, up to 12-inch long flower stems with tubular white flowers with a greenish-brown midrib.
How to keep Haworthiopsis Coarctata.
Humidity
This plant prefers dry conditions, so don't mist it. However, watering it less often can also thrive in higher humidity.
Temperature
Haworthia coarctata can withstand a wide range of temperature and humidity levels, from 32 to 75 degrees Fahrenheit. It does, however, prefer average indoor temperatures of 65-70 degrees Fahrenheit. It also prefers lower humidity, around 30–50%, but can tolerate up to 60%.
Fertilizer
Fertilizing Haworthia Coarctata is optional, but it is recommended. Feed them when they are dormant or shortly after new offsets form and grow to the size of a dime. Use an organic houseplant fertilizer at half strength to avoid getting unwanted chemicals on your plant's succulent leaves.
Pruning
Haworthia coarctata does not require pruning. If you choose to prune, use sharp, clean scissors to remove any dead leaves or flowers. Always cut above the leaf node, which is where the roots are. This will prevent disease and allow more light to reach your plant's foliage.
Toxicity
Humans and animals are not poisoned by Haworthia coarctata. However, as with any other plant, it is always best to proceed with caution. When handling, always use appropriate gloves because their sap can irritate bare skin. The toxicity of this plant is primarily due to its irritating sap, which can cause allergic reactions when it comes into contact with skin or eyes.
