Heliamphora, Sun Pitchers
Type: Carnivorous | Size: Large, Can rise to more than 120cm.
Great for terrariums the Sun Pitcher Plant (Heliamphora) is an exotic pitcher plant growing among the clouds of South America.
How to grow and care for Sun pitchers (Heliamphora)
Sun pitchers grow on the misty, wind-swept table mountains, the tepuis, of Venezuela and neighbouring Guyana. Up there the air is permanently humid, days are bright and nights are cold. Their pitchers carry a distinctive nectar spoon at the tip that lures insects to the slippery mouth.
Best terrarium setup for Sun pitchers (Heliamphora)
This is a carnivore that truly rewards a closed or highland terrarium. High, stable humidity is exactly what they evolved for, so a sealed setup with bright light and a way to drop night temperatures is ideal. Pair them with living Sphagnum moss for a beautiful, authentic tepui look.
Light
Bright light, including strong LED grow lighting, keeps them compact and brings out red pitcher tones. They can take a lot of light as long as humidity stays high.
Temperature and dormancy
The key is the day to night swing. They have no true dormancy, but they need cool nights, ideally down to around 10 to 15 degrees C, with days around 18 to 25 degrees C. Constant warm room temperature is the usual reason they slowly fail, so highland growers often use a small cooling fan or a wine fridge style setup.
Watering
Keep the Sphagnum or peaty mix permanently moist with rainwater, distilled or reverse-osmosis water only. They like it wet but airy at the roots, so living moss suits them well.
Humidity
Very high humidity, ideally 70 percent or more, which a closed terrarium provides easily. This is one carnivore where a sealed, misty environment is a genuine advantage.
Feeding
They catch their own small insects in a humid terrarium. If growth is slow you can add a tiny amount of diluted foliar orchid feed to the pitchers or leaves, but never ordinary soil fertiliser.
Common mistakes to avoid
The classic failure is warm nights: without a night-time temperature drop they sulk and rot. The other mistakes are letting humidity crash and using tap water. Give them cool nights, bright light and pure water and they are surprisingly steady.
