About Forget's Anthurium
Anthurium forgetii · also called Forget's Anthurium, Forget's Flamingo Flower · houseplant
Forget's Anthurium is a compact Colombian aroid prized for round, velvety peltate leaves with no sinus and frosted silver-white veining. Grow it in bright indirect light, a chunky bark mix kept lightly moist, and high humidity above 60%. The ASPCA lists Anthurium as toxic to cats and dogs, so site it out of reach.
Preferred mix: Chunky, fast-draining aroid/epiphyte mix
Watch for — Yellowing leaves: Usually overwatering or cold/drafty conditions causing soft yellowing and potential root rot. Check that the mix drains freely, let the top portion dry before rewatering, and keep it above 15°C.
Why forget's anthurium needs this mix
Forget's Anthurium 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 forget's anthurium 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 forget's anthurium struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Plain bagged compost packs tight around forget's anthurium'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. Forget's Anthurium needs roughly half its volume as chunky, airy material — that single change fixes most "mystery decline".
pH — does it matter for forget's anthurium?
Forget's Anthurium 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 forget's anthurium, 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 forget's anthurium 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 forget's anthurium covers the timing and technique step by step.
