Anthurium Watermaliense, commonly called the Black Anthurium, was described by L.H. Bailey and Nash in 1914 and named for the region of Watermaal in Belgium. It's native to premontane and lower montane rainforest across Central and South America — Costa Rica and Colombia especially — where it grows as a terrestrial aroid with deeply lobed, ovate-triangular leaves. Its real standout feature is the flower: a dramatic, dark violet-purple spathe surrounding an elongated spadix, giving the species its "black" nickname even though the color is technically a very deep purple.
Note: as a freshly imported bare-root plant, this specimen typically arrives with just a few leaves — the photo shows a more mature, fuller specimen for reference.
Care tip: This species blooms reliably given the right conditions — expect the striking purple spathe to fade toward green with age or lower light, which is normal rather than a sign of a problem.
Give it bright, indirect light, high humidity (50–80%), and a well-draining mix of bark, peat, and perlite. Water once the top inch or two of soil has dried, and avoid letting it sit wet — as with most Anthurium, root rot is the main risk. It's not a heavy feeder; a slow-release fertilizer a few times a year is generally enough.
A genuinely distinctive Anthurium prized for its flower rather than foliage pattern — a good pick for collectors who want the genus's dramatic bloom potential alongside its typical bold, glossy leaves.
