About Echinodorus 'Red Flame'
Echinodorus 'Red Flame' · also called Red Flame sword, red Amazon sword · tropical
A colourful sword hybrid whose broad leaves emerge green flecked with crimson and mature to deep red-spotted, fiery tones under good light. As hardy as the rest of the genus, it forms a bold rosette centrepiece, feeds heavily through its roots, and rewards bright light and iron dosing with its most intense colouration.
Preferred mix: Deep, nutrient-rich aquarium substrate with root tabs
Watch for — Loss of red colour: Low light and iron deficiency revert leaves to green. Raise lighting and dose iron heavily via root tabs and liquid iron.
Why echinodorus 'red flame' needs this mix
Echinodorus 'Red Flame' is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Echinodorus 'Red Flame' 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 echinodorus 'red flame' 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 echinodorus 'red flame''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 echinodorus 'red flame'.
pH — does it matter for echinodorus 'red flame'?
Echinodorus 'Red Flame' is not fussy about pH — a slightly acidic to neutral mix (around pH 6.0-7.0), which a standard peat-free compost provides, is perfectly fine. No testing needed.
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.
