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.

Absolutely in love with this pillow!
Size: King, Size: King
I’m so excited about this purchase — this pillow turned out to be amazing! I’m a side sleeper most of the time, and the way the edges are designed makes it incredibly comfortable and supportive. What really surprised me is that even when I slept on my back (which I normally don’t like), I felt super comfortable. I actually woke up still lying on my back — and that never happens! I know it’s healthier to sleep that way, so I’m really happy about that and hope it becomes a new habit. Before this, I tried a few regular memory foam pillows, but they always felt too firm and my neck would get tired. This one, with the shredded memory foam, is so soft and cozy — it molds perfectly without feeling lumpy. The King size is perfect too — my little Pomeranian loves to rest his tiny head next to mine on the pillow. I don’t know why he does that, but it’s adorable. And I have to mention the packaging — the box was so high-quality and beautifully made that I just couldn’t throw it away. I’m definitely keeping it to store something in. Overall, I’m super happy with this pillow and will be ordering a second one soon. I only got one to test it out, but now I’m totally convinced. Thank you for such an awesome product!

This is Truly the Best Pillow!
Size: Queen
This is the side sleeper version of the best pillow out there. My 26 year old son was always complaining about his pillow and his neck and back hurting. About every year I’d buy him the next “best” pillow promising to be the best but they never worked for him. I read an article saying THIS pillow was the “Goldilocks” of pillows. So since he sleeps in all positions, I got him the regular shaped pillow. The next morning after his first night with the pillow, he came out of his room talking about how wonderful his pillow is. Same thing the next morning. And the next. And the next. Then I thought to myself, my current pillow is the best I’ve had but I’m not in love with it. But I’m a side sleeper so I purchased this particular contoured pillow for me. NOW I UNDERSTOOD WHAT MY SON WAS TALKING ABOUT. I became the person who went on and on about my pillow. Until my husband told me to replace his with one of these side sleeping versions for himself. And he loves it. Then we got a regular pillow (for those who sleep in all positions, but this same company) for our guests. My best friend came to visit, immediately noticed the pillow upgrade from previous visits and when she returned home, she purchased one for herself. This pillow is like a feather pillow except it is filled with tiny squares of memory foam. And it comes with an extra pack of stuffing, so you can add or remove stuffing to customize it perfectly for you. None of us in the house added filling, and my son removed some that came with his pillow. I also sleep with a body pillow and have for years. And I was wishing this came in a body pillow version until I realized I could make my own. I bought a zippered body pillow case. The larger size. I think it was 54 inches long. And I bought a king size pillow and used the extra stuffing pack that came with that pillow along with the 4 packs that came with the other pillows that we didn’t use. Though you could probably do the same thing with two standard size pillows. These pillows are on the expensive side but they go on sale during every holiday. That’s when I purchase them. Oh and my body pillow is HEAVEN. Between that and the pillow, I spend my nights in fluffy cloud goodness.

Not as great as I was hoping.
Size: Queen
I was hoping this was going to be my miracle pillow. I have had terrible neck pain for years. It arrived with too much stuffing. Removed some and it caused terrible occipital headaches. I’ve slowly been adding stuffing, hoping to find the right fit.
