About Anthurium 'Black Queen'
Anthurium andraeanum 'Black Queen' · also called Black Anthurium, Black Flamingo Flower · flowering
Anthurium 'Black Queen' is a flamingo flower selection grown for its dramatic, near-black glossy spathes that open deep burgundy and darken with age, set against broad green leaves. A tropical epiphytic aroid, it flowers almost year-round indoors given bright indirect light, steady warmth, high humidity and a chunky, fast-draining mix. Note: all parts are toxic to pets.
Preferred mix: Chunky, airy aroid mix
Watch for — Root rot: Dense compost or constant wetness rots the thick roots. Use a chunky aroid mix and let the surface dry between waterings.
Why anthurium 'black queen' needs this mix
Anthurium 'Black Queen' is a climbing rainforest aroid — it wants a chunky, bark-heavy mix full of air pockets, not a dense soil that packs around its thick roots.
- In the wild anthurium 'black queen' climbs trees with thick, partly aerial roots that expect air as much as moisture — bark and perlite recreate that open structure.
- A chunky mix drains fast but the coir and compost still hold a steady reservoir between waterings, which suits its "moist then slightly dry" rhythm.
- The big air gaps stop the dense, fast-growing root mass from compacting and choking itself.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons anthurium 'black queen' struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Plain bagged compost packs tight around anthurium 'black queen''s thick roots, holds water in the centre and triggers the yellow-leaf-then-mushy-stem rot pattern.
- A fine, peaty mix with no bark leaves the roots gasping — growth slows and new leaves come out small and without fenestration.
- Too much moss or water-retaining additive keeps the core permanently wet and invites fungus gnats.
Using ordinary potting soil with no bark or perlite. Anthurium 'Black Queen' needs roughly half its volume as chunky, airy material — that single change fixes most "mystery decline".
pH — does it matter for anthurium 'black queen'?
Anthurium 'Black Queen' prefers a slightly acidic mix, around pH 5.5-6.5, which a peat-free compost-and-bark blend lands on naturally. It is not fussy enough to need testing in practice.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
Bagged "aroid mix" is now widely sold and is a fine shortcut for anthurium 'black queen', but check it actually contains visible bark and perlite — many are just rebranded compost. Mixing your own from the ratio above guarantees the structure.
Drainage and the pot
Any pot with a drainage hole works because the chunky mix does the draining. A pot only a little larger than the rootball avoids a wet, unused core; add a moss pole and the climbing roots will thank you.
Bark breaks down over time, so refresh the mix for anthurium 'black queen' every 12-18 months even if the pot size is still fine — spent, sludgy bark is a common hidden cause of decline. When the time comes, our repotting guide for anthurium 'black queen' covers the timing and technique step by step.
