Hi all

Any idea what this might be not good on Pond plants thanks in advance

I say Arum Lilly, which one though ?

Could be the native, Calla palustris.

My young ones had leaves like that.

Thanks Spotty will look into that.

Pretty certain it's Sagittarius sagittifolia, (also known as Arrowhead) not to be confused with the grass-like aquarium plant with a similar name (have to say I'm a bit confused myself to be honest!  )

Got some in the margins of my pond and it's survived everything the last 7 or so years have thrown at it.

Thanks Jay, i got it free off facebook.
