About Cat's claw
Uncaria tomentosa, commonly known as cat's claw, is a tropical woody vine native to the Amazon rainforest, capable of reaching significant lengths. Its leaves are oval and its stems feature curved, claw-like thorns, hence its name. This plant is ideal for botanical gardens or large spaces where it can climb and develop freely, though its ornamental cultivation is less common than its medicinal use.
Native range
Tropical rainforests of the Amazon in South America
Care tips
It requires full sun or partial shade for optimal growth and prefers warm, humid climates, typical of its natural environment. Watering should be frequent and abundant, keeping the substrate consistently moist but well-drained. It needs a rich, well-aerated substrate with a slightly acidic pH. A common mistake to avoid is insufficient ambient humidity and low temperatures, which can severely stress the plant.
