Top 10 hardy plants that survive genuine neglect
This list is ranked by one criterion only: what has actually survived neglect here. Missed water changes, a broken heater in February, three house moves, and two separate algae wars. Beauty was not a factor; the 60P log covers what earns their place on looks. Nurseries mentioned are where each plant usually comes from in EU shops — Tropica and Dennerle between them grow most of this list.
- Java moss (Taxiphyllum barbieri) — survived three moves, a month on a windowsill in a bucket, and one year of no maintenance at all. The only risk is it leaving the tank with you.
- Anubias barteri var. nana — rhizome plant, glue it to rock per the usual rule, and it grows at a pace that makes neglect irrelevant. A new leaf every three weeks is a healthy year.
- Java fern (Microsorum pteropus) — the thin-leaf variant handles the widest conditions of anything tested. Do not plant the rhizome; same rule as buce.
- Hornwort (Ceratophyllum demersum) — floats or plants, eats nitrate, and dies politely by shedding instead of rotting the tank. It outgrew a nitrate reading of zero during the lazy autumn of 2024.
- Cryptocoryne wendtii 'Brown' — melts when insulted, regrows when forgiven. The full autopsy is in the melt post; the short version is it always comes back.
- Vallisneria spiralis — the background filler that turned a bare right corner into a wall within two months. Expect runners; expect to pull runners.
- Bucephalandra sp. 'Biblis' — slower than everything above, but the surviving-against-odds record is unmatched, per the beginner post. Half the reason it made the list at all.
- Hydrocotyle tripartita — the slow form only. The fast form is a ground cover with ambitions; the slow form carpets at neglect-speed.
- Rotala rotundifolia — surprisingly forgiving for a "stem plant," provided the light is honest. Turns pink-ish when the tank is running well; turns leggy when you lie to yourself about the light.
- Limnophila sessiliflora — the cabomba replacement that does not dissolve. Grows under anything, thickens under anything, and asks only for a trim.
What the list is not
It is not a list of the prettiest plants, and it is not a beginner shopping list — most tanks want one or two of these, not ten. The care context for the top entries is in the buce post and the water chemistry explainer. If you want the shopping version with shops and makers, see the recommendations page.
Hardy does not mean indestructible. It means the plant files a complaint before it dies — pale leaves, slow growth, a melt that stops at the stem. Pay attention to complaints and nothing on this list ever actually dies.
