Carnivorous plants, trap by trap.
Plants that eat animals run on three rules: pure water only (rain/distilled - tap kills), nutrient-free peat mixes, and real light. Obey those and the menagerie opens - snapping flytraps, glittering sundews, drowning pitchers, millisecond bladder-vacuums. Here are 11 guides from the beginner sundew to the tepui grails, difficulty-rated without romance.
Intermediate Venus Flytrap (Dionaea muscipula)
Beginner Cape Sundew
Beginner Spoonleaf Sundew
Beginner Mexican Butterwort
Beginner Bladderwort
Intermediate Sarracenia (American Pitcher Plant)
Intermediate Nepenthes (Tropical Pitcher Plant)
Advanced Cephalotus (Albany Pitcher Plant)
Advanced Heliamphora (Sun Pitcher)
Advanced Darlingtonia (Cobra Lily)
Intermediate Byblis (Rainbow Plant)
1. Pure water only - rain, distilled or RO; tap minerals kill within months. 2. No fertilizer, no potting soil - peat+perlite/sand, hunger is the design. 3. Light - most want more sun than you think. Master these on a Cape sundew, then climb toward Cephalotus.
