Syngonium wendlandii 'Black Velvet' is a striking and sought-after houseplant, known for its unique foliage. Here are some key features:

1. Foliage: The leaves are dark green to almost black with prominent silver or white veining, giving them a velvety appearance. The leaf shape is typically arrowhead-like, which is characteristic of the Syngonium genus.

2. Growth Habit: This plant is a vining variety, making it ideal for hanging baskets or training on a moss pole for a more upright growth form. It can reach a moderate size but remains manageable indoors.

3. Light Requirements: It thrives in bright, indirect light. While it can tolerate lower light conditions, the vibrant coloration and growth may be diminished.

4. Watering: Keep the soil consistently moist but allow the top inch to dry out between waterings. Overwatering can lead to root rot, so ensure good drainage.

5. Humidity: 'Black Velvet' prefers higher humidity levels. If your home is dry, consider misting the leaves or using a humidifier to maintain a suitable environment.

6. Temperature: It prefers warm temperatures, ideally between 65°F to 80°F (18°C to 27°C).

7. Care: Fertilize during the growing season with a balanced liquid fertilizer every 4-6 weeks to encourage healthy growth.

8. Toxicity: Like other Syngonium varieties, it is mildly toxic if ingested, so keep it out of reach of pets and small children.
