Marsh Marigold - Caltha palustris

rain- · 01-07-2005, 05:22 PM

Has anyone had marsh marigold, Caltha palustris near a fishpond or in a paludarium? Here is some information about the plant and the poisonous substance it contains, glycoside, protpanemonin: Caltha palustris.

I am just wondering if it is poisonous to fish, snails and shrimps too or just humans etc. Because you can keep splitleaf philodendron, Monstera deliciosa, growing from an aquarium (only roots submersed) eventhough it is poisonous. It contains oxalic acid and not that glycoside, so it is a totally different poison. But I am trying to say that sometimes plants are poisonous only to specific species and not all. Would it be the same with marsh marigold or am I just dreaming of the impossible here?

Any help with this is appreciated

I am exploring the suitable plants for paludarium and trying not to use the most common ones =)

I've got marsh marigold growing around my pond. No problems but then it's a naturally fed pond that almost always has water flowing in and out. It is a big plant. I would think that it would outgrow most tank situations. It may also need to go dormant like a lot of northern natives.

Protoanemonin is the poison in the ranaculus family.

The first spring greens are actually edible and it's only toxic if eaten in large quantities. Still not something I'd mess with though. Easier to grow spinach or pick dandelions.

Thanks for the info

True, it really wouldn't be good for small spaces and my tank, 500 liters, 200x50x50cm, could be too small for it if it decides to grow 60cm high. That plant would certainly hit the metal halides hanging from the ceiling. Maybe I need to leave that one out of my list =)

I have been looking for something to ward off love charms. I'm a pretty hot commodity, and it's just getting to be kind of a hassle. Looks like marsh marigold might be my solution. Cheers!
