Frequently (and not so frequently) Asked Questions
BRIEF: Could Laurentia longiflora be responsible for my fish dying?
QUESTION:
I would appreciate any information on Laurentia longiflora (Star of
Bethlehem), as to it's toxins, and effects on animals, especially pond
fish, if such information is available. This plant is growing on the
berms of my pond and I am wondering if it could be the cause of some of my
fish dying.
ANSWER:
It has a cardiac glycoside similar to foxglove or oleander or lily of the
valley. It can cause nausea and GI symptoms at doses lower than those
needed to stop the heart. I don't know if enough gets into your pond to
affect the fish, though.
