With its bold, dark green foliage and striking striated texture, the Monstera Black Onyx (Monstera pinnatipartita) is an uncommon treasure for aroid lovers and design-forward plant enthusiasts. Its elongated, leathery leaves deepen in color as the plant matures, creating a dramatic contrast that feels both modern and timeless. As this climbing species develops, it begins to produce the Monstera’s iconic fenestrations—natural leaf splits that transform its foliage into living sculpture.

Native to the tropical rainforests of Central and South America, this rare cultivar of Monstera pinnatipartita is prized for its unusual coloration and strong climbing habit. With the right care, it evolves from an elegant juvenile plant into a commanding vertical specimen.

Why It’s Rare ✨

The Monstera Black Onyx is an uncommon cultivar of Monstera pinnatipartita that stands out for its exceptionally dark foliage and dramatic striations. Unlike more common Monsteras such as Deliciosa or Adansonii, Black Onyx is not widely mass-produced or tissue-cultured, making it far harder to find in mainstream plant shops.

Its rarity is further tied to its growth pattern—juvenile leaves are long and leathery, but only with age and proper climbing support do the iconic fenestrations appear. This means nurseries need years to cultivate showpiece specimens, which limits availability in the trade. Combined with high collector demand, its unique coloration and maturity transformation keep the Monstera Black Onyx firmly in the “rare aroid” category.

Why You’ll Love It 💚

  • Unique Foliage: Dark green leaves with darker striations give it a mysterious, gemstone-like appearance.
  • Maturing Beauty: Young plants show elongated leaves, while older specimens develop dramatic fenestrations.
  • Rare & Collectible: Not commonly found in cultivation, making it a standout for any rare plant collection.

Plant Care FAQs 🪴

  • Plant Type: Chill & Rare
  • Plant Vibe: Climbing Black Beauty
  • Botanical Name: Monstera pinnatipartita (‘Black Onyx’)
  • Family: Araceae
  • Light Requirements: Bright to medium indirect light
  • Watering: Allow the top 1–2" of soil to dry between waterings; avoid waterlogged soil

🏆 Pro Care Tip: Provide a moss pole or climbing support early—this plant thrives when allowed to climb, and mature fenestrated leaves will only develop if it can grow vertically. Higher humidity (65%+) also encourages fuller, healthier foliage.


Styling Tip: Showcase your Monstera Black Onyx in a tall ceramic planter with a moss pole for an elegant, upright form. Pair it with lighter-leafed Monsteras like Thai Constellation or Adansonii for dramatic contrast in a rare plant display.

🍵 Tea Pairing: Pair with a cup of dark oolong tea—the deep, roasted notes echo the plant’s rich, dark foliage.

⚠️ Please note: The plant you receive may not be the exact one pictured, but it will be of the same type and size. Each plant is unique! Expect natural variation in color, leaf shape, and size. Cosmetic blemishes are normal and do not impact plant health.

7 Amazing Benefits of Houseplants

Boost Aesthetics:
Houseplants bring life and beauty to any space, softening harsh lines and adding natural elegance to your home or office. They even help screen views, fill empty spaces, and reduce noise, transforming your environment.

Purify the Air:
According to NASA, houseplants clean the air by removing toxins like carbon monoxide and formaldehyde, making your indoor spaces fresher and healthier. They also increase humidity, reducing dry skin and respiratory issues, especially during winter.

Enhance Mood & Productivity:
Plants aren't just beautiful—they make you feel good! Studies show that plants reduce stress, improve happiness, and boost concentration and memory by up to 20%. They’re also known to increase productivity and creativity in workspaces.

Therapeutic & Healing:
Caring for plants is therapeutic. Houseplants have been shown to reduce anxiety, depression, and even speed up recovery from illness or surgery, making them a great addition to your living space or even hospital rooms.

Increase Focus & Attention:
Live plants enhance focus and attention. Whether you're studying or working, having plants nearby helps you stay alert and concentrated, making them perfect companions for study areas and offices.

Job Satisfaction:
Adding plants to your office can lead to greater job satisfaction and a positive outlook. Research shows that employees working around greenery feel happier, more productive, and more connected to their workplace.

Improve Air Quality:
Plants are natural air purifiers, reducing harmful pollutants and refreshing the air. Species like spider plants, bamboo palms, and rubber trees help cleanse your indoor air, making your home healthier.

Watering

Houseplants have varying water needs depending on their growth and seasonal changes, so it's best to water as needed rather than on a schedule. Generally, water when the top 1/2 to 1 inch of soil is dry. Cacti need less water, while flowering plants may need more. Avoid overwatering, as it's a common cause of plant death. Water carefully to prevent leaf disease.

Fertilizing

Fertilizing houseplants depends on their growth rate, age, and season. Spring and summer are ideal for fertilizing as plants grow more, while little to no fertilizer is needed in fall and winter. Avoid overfertilizing, as it can burn roots. For flowering plants, use a balanced fertilizer and ensure it includes micronutrients to prevent deficiencies.

Plant General Care

Cleaning: Most houseplants benefit from regular cleaning to look their best. Dust tends to accumulate on leaves, so rinse them gently with room-temperature water. For plants with hairy leaves, use a soft brush to avoid trapping moisture. Smooth-leaved plants can be wiped with a soft cloth. This not only enhances their appearance but also helps them absorb more light.

Pruning: You can prune houseplants year-round, but fall is a great time to trim them after a summer of growth. Pruning helps improve their appearance and control size. Cutting back overgrown plants to 4-6 inches encourages rejuvenation, especially for trailing plants like Swedish ivy and pothos. Make cuts just above buds or side shoots to promote new growth, and remove any dead or diseased leaves to prevent spreading.

Pinching, which involves removing stem tips, encourages fuller, more compact growth. Simply pinch or cut the top leaves to stimulate side bud growth. Fast-growing plants benefit from regular pinching to maintain their shape.

Repotting: Check the roots—if they're circling the inside of the pot, it's likely time to repot. You can transplant into a slightly larger container or, if you prefer to keep the same pot, trim some of the roots and refresh the soil. Repotting is also a great time to divide plants with multiple stems to create new ones. Spring and summer are ideal for repotting.

Insects & Disease

Insects:

Several insects can attack houseplants, but insecticidal soap is an easy and effective treatment for most soft-bodied pests like aphids and spider mites. A strong spray of water can also help reduce their numbers. For insects with waxy coatings, such as scale and mealybugs, rubbing alcohol applied with a cotton ball works well.

Consistency is key—fast-reproducing pests like aphids and spider mites may need weekly treatments for about a month to fully eliminate them.

Fungus gnats, often mistaken for fruit flies, are common when plants are overwatered. Let the soil dry between waterings and remove any dead leaves from the soil surface. In severe cases, repotting the plant in fresh soil and a clean container may be necessary.

Plant Disease

To prevent the spread of plant diseases, promptly remove and destroy affected houseplants, leaves, or stems as soon as symptoms appear. Controlling insect populations can also help, as some diseases spread via pests. Common houseplant diseases and their treatments include:

  • Powdery Mildew: Appears as powdery white spots on leaves.
  • Fungal Leaf Spots: Yellow, brown, or black spots on leaves.
  • Root Rot: Mushy, dark-colored roots, usually caused by overwatering.
