Heliamphora ( Sun Pitchers )

These grow on the mountains in Venezuela where they receive lots of sun, humidity, water and cool temperatures, which drop significantly at night. All of which makes them a challenging plant to grow. I’ve slaughtered many.

First discovered in 1839 by explorers there are many species. The mountains are flat topped and widely separated leading to many similar, but different plants.

These are carnivores, but use a bacteria in the pitcher fluid to break down the insects instead of producing their own enzymes. There was and is an ongoing debate as to how carnivorous they are.

Outside through the Houston fall-winter-spring they do very well. It’s too warm in the summer for Heliamphoras to be outside. I have two growing quite well in terrariums, one on a windowsill that gets lots of morning light, one in a niche that has a light directly over the terrarium.

Humidity seems to override all other things when growing Sun Pitchers. Bright light is next and like all carnivorous plants distilled water is best. I’ve not found a daily temperature change to be important for growing, it might be for flowering? Every time I’ve removed it from the terrarium it’s begun to die back, starting by browning at the top edge of the pitchers.
