Few houseplants command attention quite like a rare Anthurium. With their deeply veined, velvety leaves — some growing to over a metre long — these Colombian cloud-forest natives are the kind of plant that stops visitors mid-sentence. They are not the easiest plants to grow, but for collectors willing to meet their needs, the reward is extraordinary.
Anthurium Care at a Glance
- Light: Bright, indirect light — no direct sun
- Water: Moderate; keep evenly moist but never waterlogged
- Humidity: High — 60–80% for rare velvet-leaf species
- Temperature: 65–80°F (18–27°C); avoid cold drafts
- Soil: Chunky, well-aerated mix with excellent drainage
- Fertilizer: Light feeding every 3–4 weeks during active growth
- Pet safety: Toxic to cats and dogs if ingested
- Difficulty: Intermediate to advanced
Light Requirements
Anthuriums grow naturally on the shaded floors and slopes of tropical cloud forests, filtered by a dense canopy above. In your home, replicate this with bright, indirect light — a north- or east-facing window is ideal, or a few feet back from a bright south or west window.
Direct sun will scorch the leaves quickly, especially on velvet-leaf varieties whose dark, light-absorbing surfaces are particularly vulnerable. Signs of too much light include bleached patches, crispy edges and faded colour. Signs of too little include slow growth, small new leaves and loss of deep colour.
Grow lights work well for Anthuriums, especially in darker homes or during winter. A full-spectrum LED positioned 30–45 cm above the plant for 12–14 hours a day can substitute effectively for natural light.
How to Water an Anthurium
Anthuriums want to stay evenly moist — not wet, not bone dry. Unlike Hoyas, they do not appreciate a full dry-out between waterings. The goal is a potting mix that feels like a wrung-out sponge: damp throughout, but not dripping.
Water when the top 2–3 cm of the mix feels dry to the touch. Water thoroughly, allow it to drain completely, and never leave the plant sitting in a saucer of water.
Use room-temperature water. Anthuriums are sensitive to fluoride and chlorine — if your tap water is heavily treated, allow it to sit overnight or use filtered water, especially for rare velvet-leaf species like A. warocqueanum.
Reduce watering frequency in winter or whenever growth slows. Overwatering is the most common cause of Anthurium decline — yellowing lower leaves and soft, dark roots are the warning signs.
Humidity: The Most Important Factor for Rare Species
This is where most growers struggle. Common Anthuriums (the flowering types sold in supermarkets) tolerate average household humidity. Rare velvet-leaf species do not.
The Queen Anthurium (A. warocqueanum) originates from Colombian cloud forests where humidity rarely drops below 70%. In dry indoor air, the leaf edges will brown and crisp, new leaves may fail to unfurl properly, and growth will stall.
Aim for 60–80% relative humidity for rare species. Practical ways to achieve this:
- A dedicated room humidifier (most effective)
- A humidity tent or grow cabinet for the most demanding species
- Grouping plants together to create a microclimate
- A pebble tray with water beneath the pot (modest effect)
Avoid misting directly onto leaves — it can encourage fungal issues without meaningfully raising ambient humidity.
The Best Soil for Anthuriums
Anthuriums are epiphytes or semi-epiphytes in nature, meaning their roots need excellent aeration. Dense, moisture-retaining potting soil is a common cause of root rot.
A reliable Anthurium mix:
- One part high-quality potting mix or coco coir
- One part orchid bark (medium grade)
- One part perlite or pumice
- Optional: a small amount of worm castings for slow-release nutrition
Always use a pot with drainage holes. Terracotta can help prevent overwatering by wicking excess moisture. For rare species in high-humidity setups, plastic pots may be preferable to prevent the mix drying too quickly.
Fertilizing
Feed lightly during active growth (typically spring through early autumn) with a balanced liquid fertilizer diluted to half strength, every three to four weeks. Anthuriums are not heavy feeders — more fertilizer does not mean faster growth, and excess salts can damage sensitive roots.
Flush the pot with plain water every couple of months to clear accumulated salts. Pause feeding during winter or whenever the plant is not actively growing.
Common Anthurium Problems
Brown Leaf Edges
The most common complaint with rare Anthuriums, and almost always caused by low humidity. Increase ambient humidity before adjusting anything else. Fluoride sensitivity can also cause tip burn — switch to filtered water if browning persists despite good humidity.
Yellow Leaves
Usually overwatering or poor drainage. Check the roots — healthy Anthurium roots are white or pale tan. Dark, mushy roots indicate rot. Trim affected roots, allow to dry briefly, and repot into fresh, airy mix.
Leaves Failing to Unfurl
New leaves that emerge crinkled, stuck or deformed are a classic sign of insufficient humidity during the leaf's development. This is particularly common in A. warocqueanum. Raise humidity and be patient — the next leaf often emerges normally once conditions improve.
Slow or No Growth
Anthuriums are naturally slow growers, especially rare species. In low light or cool temperatures, growth may pause entirely. Ensure bright indirect light, consistent warmth and adequate humidity before assuming something is wrong.
Pests
Check regularly for thrips, spider mites, mealybugs and scale. Thrips are particularly damaging to Anthuriums — they feed inside developing leaves, causing silvery streaking and distorted growth. Inspect new growth closely and isolate any affected plant immediately.
Are Anthuriums Toxic to Pets?
Yes. All Anthuriums contain calcium oxalate crystals and are toxic to cats, dogs and humans if ingested, causing oral irritation, drooling, vomiting and difficulty swallowing. Keep them out of reach of pets and children. If you are looking for equally dramatic but pet-safe alternatives, browse our Non-Toxic & Pet Safe collection.
Collector Notes: Queen Anthurium & Podophyllum
Two of our most sought-after Anthurium species deserve special mention:
Anthurium warocqueanum 'Queen Anthurium' — The benchmark velvet-leaf Anthurium. Leaves can reach over a metre in length with age, displaying deep green velvet texture and prominent silver veining. Demands high humidity and patience, but is one of the most visually spectacular houseplants available to collectors.
Anthurium podophyllum — A more unusual species with deeply lobed, palmate leaves that give it an almost prehistoric appearance. Partial shade and moderate watering suit it well, making it slightly more forgiving than the velvet-leaf species.

Tips for Success
- Invest in a hygrometer — knowing your actual humidity level removes the guesswork.
- A grow cabinet or IKEA greenhouse cabinet can transform results for demanding species.
- Rotate the plant occasionally so all sides receive even light.
- New leaves emerge from a sheath called a cataphyll — leave it in place until it dries naturally.
- Repot in spring, only when roots are visibly circling or escaping the pot.
- Patience is essential. A healthy Anthurium producing one spectacular new leaf every few weeks is performing exactly as it should.
Final Thoughts
Rare Anthuriums are not beginner plants — but they are not impossibly difficult either. The fundamentals are straightforward: bright indirect light, consistent moisture, excellent drainage and, above all, high humidity. Get those right and these extraordinary plants will reward you with some of the most dramatic foliage in the houseplant world.
