About

Anthurium watermaliense is grown less for its foliage than for its flower — a deeply lobed, glossy dark green leaf sets off a spathe so deeply pigmented it reads as near-black, giving rise to its "Black Anthurium" common name. It is a terrestrial to hemiepiphytic cloud-forest species from Colombia and Ecuador, and while it can be grown for foliage alone, most collectors seek it out specifically for a mature specimen in bloom.

Before You Buy

Species-specific things to check when evaluating a listing

  • Check root health — firm, white to tan roots, avoiding black or mushy ones
  • If buying for the flower, confirm with the seller whether the plant has bloomed before, since juvenile plants may not flower for years
  • Inspect leaf undersides for scale and mealybugs

Cultivar character is preserved through vegetative cuttings

Divide established clumps at the root mass; seed-grown plants take considerably longer to reach flowering size.

Care Guide

Growing Conditions

Substrate

Chunky, highly aerated aroid mix: 40% orchid bark, 30% perlite, 20% potting compost, 10% charcoal.

Watering

Keep lightly moist; avoid letting the substrate dry out completely between waterings.

Humidity

65-85% preferred — a cloud-forest species that struggles in dry indoor air.

Fertilising

Balanced liquid fertiliser at quarter strength every 4 weeks in spring and summer.

Repotting

Every 18-24 months, or when roots fill the pot.

Common Problems

Problem

No flowering

Cause

Plant is immature, or insufficient light/nutrients

Fix

Mature plants need several years and consistently good light/feeding to reach flowering size

Problem

Brown leaf edges

Cause

Low humidity

Fix

Increase ambient humidity — this species is more humidity-sensitive than common Anthurium hybrids

Field Notes · Vol. 11 August 2024

Bought for the Bloom

Watermaliense is unusual among collector Anthuriums in that the point of the plant is arguably its flower rather than its foliage — that near-black spathe is genuinely striking and the reason the species commands the prices it does. Patience is required; a juvenile plant purchased for foliage alone may take years to reach blooming maturity.
