I visited Acorn Bank (NT) up in Cumbria towards to the end of April, and
came across a plant that I couldn't place. I'm not sure whether it was
meant to be there, or arrived under it's own steam.

Anyone recognise it?

There was also in the woodland garden there (and I presume wild) a
marginal plant that is reasonably common, but which I've never pinned
down.

While I'm asking questions, there's also this aquatic plant photographed
in a canal backwater last month.

They are tough so I cannot help much; 1 looks just like Chrysosplenium
oppositifolia in habit but the petals are way too big. It is a
common native in damp woodlands. 3 could be a Callitriche which are
common aquatics in steams and ditches and are buggers to tell apart.
