About Anubias barteri var. nana 'Petite'
Anubias barteri var. nana 'Petite' · also called Anubias nana Petite, mini Anubias · tropical
Anubias barteri var. nana 'Petite' is the miniature cultivar of dwarf Anubias, with tiny leaves barely two centimetres long. It is the go-to foreground accent for nano aquascapes, attached to small stones or branches. As hardy and slow as its parent, it thrives in low light and feeds from the water column.
Preferred mix: Rhizome attached to small hardscape, never buried
Watch for — Detachment from hardscape: Small plants can pop loose before roots grip. Re-secure with gel glue or thread until the roots anchor firmly.
Why anubias barteri var. nana 'petite' needs this mix
Anubias barteri var. nana 'Petite' is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Anubias barteri var. nana 'Petite' is adaptable, but like most houseplants it still needs air at the roots — a mix that drains freely while holding a working moisture reserve.
- A little perlite or bark stops ordinary compost compacting into an airless block over time, which is the slow, common cause of decline.
- It is not fussy about pH or special ingredients; getting the air-to-moisture balance right is what matters.
For the full picture on what makes up a good mix, see our guide to the main types of soil and potting media — it explains why each ingredient above behaves the way it does.
What goes wrong with the wrong mix
The wrong soil is one of the most common reasons anubias barteri var. nana 'petite' struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Plain garden soil or a cheap, claggy compost compacts in the pot and slowly suffocates anubias barteri var. nana 'petite''s roots.
- A pure peat mix that dries to a hard, water-repelling block is hard to re-wet and stresses the plant.
- No drainage hole turns even a good mix into a stagnant, root-rotting sump.
Reusing tired, compacted old compost or skipping the perlite. A free-draining mix in a pot with a hole solves most "why is it struggling" cases for anubias barteri var. nana 'petite'.
