About Red Dragon Venus Flytrap
Dionaea muscipula 'Akai Ryu' · also called Red Dragon Venus flytrap, Akai Ryu Venus flytrap · houseplant
Dionaea muscipula 'Akai Ryu' (Japanese for 'Red Dragon') is a cultivar of the Venus flytrap developed by Ron Gagliardo at Atlanta Botanical Garden and registered in 1997, distinguished by its all-over deep burgundy-red colouration from petioles to trap lobes. Like the species, it is native to the subtropical bogs of coastal North and South Carolina in the United States and requires a winter dormancy period of cooler temperatures and shorter days. The single most critical care rule is to water exclusively with distilled, rainwater, or reverse-osmosis water — tap water minerals cause irreversible root damage. According to the ASPCA, Dionaea muscipula is non-toxic to cats, dogs, and horses.
Preferred mix: 1:1 sphagnum peat and perlite, or pure long-fibred sphagnum moss
Why red dragon venus flytrap needs this mix
Red Dragon Venus Flytrap is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Red Dragon Venus Flytrap 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 red dragon venus flytrap 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 red dragon venus flytrap'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 red dragon venus flytrap.
pH — does it matter for red dragon venus flytrap?
Red Dragon Venus Flytrap 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.
