Anthurium watermaliense

Anthurium watermaliense is the accepted species behind the common names Black Anthurium and Black Prince, both used for its dark violet-purple spathe. The foliage itself is glossy green, deeply lobed and held from a short, thick-rooted crown.

The plant can grow terrestrially or occasionally epiphytically in wet tropical habitats. In cultivation, it needs steady moisture, warm conditions and an open substrate that keeps oxygen around the roots.

Recognising Anthurium watermaliense

  • Foliage: Deeply lobed, cordate leaves with a glossy to semi-glossy upper surface.
  • Inflorescence: Dark violet-purple spathe, often the reason for the Black Anthurium nickname.
  • Growth habit: Short-stemmed Anthurium with thick roots and a self-standing crown.
  • Cataphylls: Protective leaf sheaths can wear into fibres around the stem.
  • Origin: Native from Costa Rica to Colombia in wet tropical habitats.
  • Root structure: Dense roots need moisture and air rather than compact, saturated substrate.

Leaves, roots and spathe of Anthurium watermaliense

Anthurium watermaliense has lobed, glossy leaves with a paler underside and a compact stem that stays close to the pot. Mature plants can produce a dark spathe that may appear almost black in certain light, although botanically it is better described as deep violet-purple.

The thick roots need moisture and oxygen at the same time. A bark-rich aroid mix keeps the root zone open, while regular but measured watering prevents the crown from sitting in stale, saturated substrate.

Indoor care for Anthurium watermaliense

  • Light: Bright filtered light keeps the leaves firm and reduces scorch risk on glossy surfaces.
  • Watering: Keep the mix lightly moist, then let excess water drain fully after each watering.
  • Substrate: Use an airy organic aroid mix with bark, coarse fibre and mineral structure.
  • Humidity: Moderate to high humidity keeps new leaves and inflorescences from drying at the edges.
  • Temperature: Warm, stable conditions are important; cold wet roots can decline quickly.
  • Potting: Keep the crown slightly above the substrate surface so the short stem stays dry and ventilated.
  • Feeding: Feed lightly during active growth and flush the pot occasionally to reduce salt marks on leaf edges.

Leaf, root and spathe issues on Anthurium watermaliense

  • Soft yellowing leaves: Check drainage and root condition, especially if the substrate feels dense or sour.
  • Brown edges: Low humidity, inconsistent watering or fertiliser salts can mark the leaf margins.
  • Damaged spathe: Dry air, handling or transport can crease or dry the dark spathe.
  • Pest marks: Inspect new growth, petioles and leaf undersides for thrips, mites and mealybugs.

Plant safety with Anthurium watermaliense

Keep Anthurium watermaliense away from pets and small children. Like other Anthurium species, it contains calcium oxalate crystals that can irritate the mouth, throat, skin and eyes.

Botanical notes on Anthurium watermaliense

Anthurium watermaliense was described by L.H.Bailey and Nash and published in 1914. It is an accepted Araceae species native from Costa Rica to Colombia. The genus name Anthurium refers to the tail-like spadix of the inflorescence.

Great for chewers
Color: Knuckle Bone, Size: XX-Large
I have a 13 month old 56 lb boxer/rottie mix who is a medium chewer and this bone is great for him. No splintering, doesn't make a mess, and hard enough to make him work without any danger of him breaking teeth, getting cut, or choking. We gave it to him a couple of weeks ago and based on wear I'm confident it will last him a long time (many months at least). I was a little hesitant about giving my animal a product that contained nylon, but after a scary experience giving a rawhide bone to a previous foster dog, I was told this was a much safer option and now I agree. This bone is very dense and very hard, so it makes an awful noise when my dog drops it on my hardwood floor. We are also careful to make sure he doesn't drop it on our bare toes, because that would be quite unpleasant. Be aware that the chewed edges also get really rough because of the way the bone wears, so they can become a magnet for dog hairs or fabric threads. This hasn't been a problem for us (we just encourage our pup to chew it on his bed and take it away from him when we are watching a movie so the noise isn't bothersome), but it is good to know. Update: We've had Winston for 5 months now and in that time he has gained 5 lbs of muscle. He loves his Nylabone! It is still going strong and I think he will be able to use this well through his one year adoptiversary. The only issue we have with this bone is that the edges can get sharp and sometimes will cut his mouth. He doesn't notice and just wants to keep chewing, but we usually take the bone away at that point for a bit. My boyfriend has taken the bone and used a power sander on it a few times now to remove all the sharp edges. We only have to to in once every couple of months but it makes a big difference.

The best toy my dog has
Color: Monster Bone, Size: XX-Large
Our lab mix is a very ambitious chewer - forget retrieving... he seems to think his "job" in life is to destroy things with his teeth. He's very methodical about it; he'll chew and chew and chew, targeting the object's weakest points, until all that remains is a littering of coin-sized remnants. He even started to make progress on his heavy duty black Kong within about a week. By the time he was about 8 months old, we figured out that the only toys he can be left alone with are the ones made by Nylabone. He has all their models: dinosaurs, rings, small bones, and branches. These Nylabone toys are a hard plastic that chips off in tiny little shards. He's happy because he feels like he's making progress (even though it takes him a long time to do so) and we're happy because the toys last a relatively long time and he can't swallow anything that might hurt him. He does leave tiny plastic shavings on the carpet, but we have to vacuum a lot anyways because of his fur, so it's not a big deal. Of all his Nylabone toys, this is the best (and probably his favorite of the bunch). He really likes the size - just right for him to prance around with and show off. Although he's had it for four months, it's still smooth enough in the middle that we can hold it for him comfortably, and it's retained its original shape (unlike dinosaur and branch). If we could just train him not to drop this on our feet when he wants attention(it weighs a few pounds and has gotten a bit pokey on the ends)this would be the perfect toy.

Cute squeaky toy, good price.
Size: Pack of 3, Color: Mini Loofa
These little squeaky toys are one of my yorkie pups favorite. Being latex they are last longer than the material ones. Good price for the 3 pack.
