Black Raven ZZ, dark zz plant in 6" pot, Zamioculcas zamiifolia raven

Note: You will receive a Black Raven ZZ in a 6" pot, similar to the pictures.

The Black Raven ZZ (Zamioculcas zamiifolia) is a unique variety of the popular ZZ plant, known for its dark, glossy, almost black foliage. This variety is just as hardy and easy to care for as the original ZZ, but with a more dramatic, visually appealing look. Native to East Africa, the ZZ plant is celebrated for its resilience and ability to thrive with minimal attention.

Light Requirements

• Low to Bright Indirect Light: The Black Raven ZZ adapts to a variety of lighting conditions, from low light to bright indirect light. Growth may slow in lower light environments.
• Ideal Lighting: For optimal growth, place the plant in medium to bright indirect light. It will grow more vigorously and stay healthier.
• Avoid Direct Sunlight: Direct sunlight can scorch the dark leaves, causing them to yellow or brown. Place near a window with sheer curtains or in a room with natural light but no direct sun exposure.

Watering

• Watering Needs: The Black Raven ZZ is drought-tolerant and should dry out completely between waterings. Overwatering is the leading cause of root rot in ZZ plants.
• Watering Frequency: Water every 2-3 weeks during the growing season (spring and summer). In fall and winter, water once a month or when the soil is dry.
• Signs of Overwatering: Yellow or mushy leaves indicate overwatering or poor drainage. Ensure the pot has drainage holes to prevent water pooling.
• Watering Tip: Check soil moisture by sticking your finger 1-2 inches deep. If dry, water the plant. If moist, wait a few more days.

Temperature

• Warm Temperatures: The Black Raven ZZ thrives between 65°F to 75°F (18°C to 24°C). Avoid temperatures below 50°F (10°C).
• Indoor Care: Keep the plant in a room with stable temperatures and avoid placing near drafts, air conditioners, or heaters.

Soil

• Well-Draining Soil: Like all ZZ plants, it requires well-draining soil. A cactus or succulent mix works well, or add perlite or sand to regular potting soil to improve drainage.
• Soil pH: Prefers slightly acidic to neutral soil (pH 6.0 to 7.0).
• Avoid Heavy Soils: ZZ plants don’t tolerate waterlogged soil, so use light, well-aerated soil.

Fertilizing

• Minimal Fertilizing: The Black Raven ZZ is a slow grower and doesn't require frequent fertilizing. Feed only during the growing season (spring and summer).
• Fertilizer Type: Use a balanced liquid fertilizer (e.g., 10-10-10) diluted to half strength. Fertilize once a month during the growing season, but avoid in fall and winter.
• Avoid Overfertilizing: Over-fertilizing can lead to salt buildup in the soil, causing leaf burn. Stick to a conservative fertilizing schedule.

Pruning and Maintenance

• Minimal Pruning: The Black Raven ZZ doesn’t require regular pruning. Remove dead or yellowing leaves as needed.
• Cleaning the Leaves: Dust can reduce photosynthesis. Gently wipe the leaves with a damp cloth to keep them shiny and clean.
• Stem Care: The stems are sturdy. Cut only damaged or excessively long stems. Trim at the base if necessary.

Pests and Problems

• Common Pests: ZZ plants are pest-resistant but may attract:

  • Mealybugs
  • Scale
  • Spider mites

• Pest Control: Treat infestations with neem oil, insecticidal soap, or a mild alcohol-water solution (70% rubbing alcohol mixed with water).

• Yellowing Leaves: This often indicates overwatering. Check soil moisture and adjust watering.

• Leaf Drop: If leaves drop or the plant looks unhealthy, it could be due to stress from overwatering, cold temperatures, or insufficient light. Ensure the plant is in a warm, bright area and avoid overwatering.

Repotting

• Slow Growth: The Black Raven ZZ grows slowly, so it doesn’t need frequent repotting. Repot every 2-3 years or when the plant outgrows its pot.
• Choosing a Pot: Select a pot that is only 1-2 inches larger in diameter than the current one. ZZ plants prefer to be slightly root-bound.
• Repotting Tip: Ensure the new pot has good drainage to prevent water from collecting at the bottom, which can cause root rot.

Toxicity

• Toxic to Pets: The Black Raven ZZ is toxic to cats, dogs, and other pets. It contains calcium oxalate crystals that can cause irritation if chewed or ingested.
• Symptoms of Toxicity: Ingesting any part of the plant may cause drooling, vomiting, or difficulty swallowing. Contact a vet if you suspect your pet has ingested it.

Propagation

• Propagation by Leaf or Stem Cuttings: ZZ plants can be propagated by leaf or stem cuttings, but the process is slow.

  • Take a healthy leaf or stem with a portion of rhizome attached.
  • Place the cutting in well-draining soil and keep moist (not soggy).
  • Provide indirect light and wait for roots to form, which can take a few months.

• Propagation by Division: You can propagate by dividing the rhizomes when repotting. Gently separate the rhizomes into smaller sections, each with stems and roots. Plant them in separate pots.
