Byblis Liniflora
IntermediateByblis liniflora
An Australian carnivorous plant with rainbow-glistening mucilage, called Rainbow Plant.
About
Byblis liniflora, the rainbow plant, is an annual carnivorous plant native to the tropical wetlands and grasslands of northern Australia (Northern Territory and northern Queensland) and Timor. Its common name refers to the spectacular iridescent shimmer produced by the dense, gland-tipped mucilaginous tentacles covering its thread-like leaves—a prismatic rainbow effect in sunlight. Like all Byblis, it captures insects passively by adhesion to this sticky surface but lacks the ability to move its tentacles or leaves. It is treated as an annual in cultivation, germinating in autumn to spring and completing its cycle the same season. Seed germination may benefit from smoke treatment (smoke water soaking) as in other Australian fire-adapted flora.
Lifespan of the Byblis Liniflora
The Byblis Liniflora lives 1-2 years (annual).
Size of the Byblis Liniflora
The Byblis Liniflora grows to 10-30cm.
Temperature & humidity for the Byblis Liniflora
The ideal temperature for the Byblis Liniflora is 20〜35℃.
Cultivation uses sphagnum or peat-perlite media, tray watering with pure or rainwater, and full sun with warm temperatures (20–35°C).

Growing Tips
Light & Placement
It likes strong direct sun with warm, humid conditions, so grow it in a sunny spot. It stretches easily when light is insufficient.
Watering
Keep the medium constantly moist with tray watering, using purified water or rainwater. Avoid mineral-rich tap water.
Temperature & Overwintering
Ideal conditions are warm and humid at 20-35°C. As an annual it dies back, so overwinter it as seed rather than as a plant.
Soil & Repotting
Use moist sphagnum alone or a peat moss and perlite mix. As an annual it generally does not need repotting.
Propagation
Sow seed in autumn to winter, let it grow, flower and set seed in spring to summer, then collect seed. Soaking seed in smoke-treated water can improve germination.
