I took this photo as part of a reply on to the water in pitchers question on another forum. As stated there this is a small group of Sarracenia purpurea which have not had water in their pitchers for many many years. There are S. purpurea ssp. purpurea, ssp. venosa and ssp purpurea heterophylla in there and a few other bits and pieces. Not having water in the pitchers doesn't appear to have done them any harm as they flower profusely annually.  |

That's very interesting Fred.
Presumably the traps do get prey within them?, but are to all intent and purposes are dry, in as much as no water is introduced from external sources. That would suggest that the inquilines must be still present and breaking down the prey in a dry trap state for absorption of the inorganic elements by the plant, otherwise they would not have survived as well as they have for the last years.
Do you ever see signs of scorching on the leaves from excess nutrient concentration from dissolving prey?
Cheers
Steve

S. purpurea is an awful carnivore without water in the pitchers Steve. I think the only prey I've ever seen them get are the very occasional slug, and I've no idea why the slug died in there.
S. psittacina seems to do fine in collections and I doubt any of those catch prey unless they're semi-aquatic.
I have a Slack hybrid which has an enormous mouth so it catches nothing, even a 747 could turn and fly out of it. That's been going for years.

All my sarrs live outside year round and the purps are filled naturally with rainwater. The psittacina seem to do well despite not being half submerged. Perhaps i should selectively feed them.
