About Shark Teeth Venus flytrap
Dionaea muscipula 'Shark Teeth' · also called Shark Teeth Venus flytrap, Shark Teeth flytrap · houseplant
A collector cultivar whose trap lobes are lined with broad, triangular, shark-fin teeth without serrations — giving the open trap the unmistakable look of a gaping shark jaw. Grows erect in summer, prostrate during winter dormancy. Like all Venus flytraps, it demands pure water, full sun, and nutrient-poor soil. Pet-safe per ASPCA.
Preferred mix: Nutrient-poor acidic carnivore mix
Why shark teeth venus flytrap needs this mix
Shark Teeth Venus flytrap is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Shark Teeth 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 shark teeth 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 shark teeth 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 shark teeth venus flytrap.
pH — does it matter for shark teeth venus flytrap?
