2. Genus General Profiles & Core Parameters
Dionaea muscipula (Venus Flytrap)
Monotypic genus native to the coastal bogs of North and South Carolina. Known for its rapid thigmonastic snap-traps.
- Light Requirements: Full outdoor direct sunlight (1,000+ µmol/m²/s or high-output LED arrays)
- Substrate Formula: 50/50 fine sphagnum peat moss and horticultural perlite.
- Moisture Management: Stand in 1–3 cm of pure RO water (<50 ppm TDS) during spring/summer. Remove trays in winter.
- Seasonal Cycle: Mandatory 3–4 month cold winter dormancy (2–10°C) required to prevent crown exhaustion.
Sarracenia (North American Pitcher Plants)
Herbaceous perennials producing erect, trumpet-shaped pitchers that act as pitfall traps. Exceptional outdoor bog plants.
- Light Requirements: Unfiltered, direct outdoor sunlight.
- Substrate Formula: 50/50 peat moss and coarse perlite or quartz sand.
- Moisture Management: Keep heavily watered in deep trays throughout active growth. Reduce in winter to prevent root rot.
- Key Genera/Species: S. purpurea, S. flava, S. leucocephala, S. alata.
Pinguicula (Mexican & Subtropical Butterworts)
Small rosettes featuring glandular, sticky carnivorous leaves. Renowned for their vibrant floral displays and windowsill adaptability.
- Light Requirements: Bright indirect light or east-facing windowsills; highly responsive to indoor LED lighting.
- Substrate Formula: Mineral-heavy mix (equal parts perlite, silica sand, pumice, and peat) or standard 50/50 peat/perlite.
- Moisture Management: Keep damp during summer growth. Transition to near-dry conditions during the winter non-carnivorous succulent phase.
- Key Species: P. ehlersiae, P. esseriana, P. gigantea, P. moranensis, P. cyclosecta and a whole load of Hybrids.
Drosera (Sundews)
One of the largest genera of carnivorous plants, utilizing glandular tentacles topped with sticky mucilage drops.
- Light Requirements: High-intensity light to promote brilliant red pigmentation and thick mucilage production.
- Substrate Formula: Pure sphagnum peat and perlite or live long-fiber sphagnum moss.
- Moisture Management: Continuous open-air tray system in pure water (<50 ppm TDS).
- Terrarium species: top of this list must be D. adelae and D. prolifera.
- Key Species: D. capensis (Cape Sundew), D. aliciae, D. spatulata, D. binata.
Nepenthes (Tropical Pitcher Plants)
Lianas and climbing vines native to Southeast Asia, producing complex passive pitfall traps (pitchers) at the ends of leaf tendrils.
- Light Requirements: High, dappled indirect light or specialized 14-hour LED growth cycles.
- Substrate Formula: Highly porous, airy media: long-fiber sphagnum moss, perlite, and coarse orchid bark/coir chips.
- Moisture Management: Continuous drainage. Water thoroughly from top when upper layer dries slightly. Do not leave standing in water trays.
- Environmental Groups:
- Lowland: High heat (28–35∘C daytime), high night temps, high humidity all year around.
- Intermediate: Mid range and the most forgiving of the 3 ranges.
- Highland: Warm daytime (22–26∘C), mandatory cool, must experience a night drop of at least 10∘C+ to survive long term.
- Strong variety’s: Fortunately there are not only very strong species like N. ventricosa and N. maxima but there are loads of hybrids stemming from them like N. ‘Gaya’ and others, that are easy to keep healthy even in Gauteng.
