Why Terrariums Fail for Temperate Carnivorous Plants

Venus Flytraps, Sarracenia, and Most Sundews Need Seasons, Not Terrariums

A 25‑gallon aquarium with flytraps, sundews, and pitchers will result in weak, etiolated plants that eventually die. These species require:

• Full sun (or very strong artificial light).
• Seasonal dormancy (cold winter rest).
• Excellent air circulation.

Better Terrarium Candidates

• Cephalotus follicularis
• Pinguicula (Mexican species)
• Some Utricularia and Drosera (tropical only)

For a communal display, use a bog garden outdoors or a greenhouse. Join the FlytrapCare forums for terrarium‑specific advice.
