Two Flowers

New to me on Blacka and fortunate to be where sheep and cattle can't get at them.

This one should be easier being on the edge of the woods and being the only vetch like flower in my books that is white, the wood vetch.

But this is a puzzle. Its leaves are like nettle and its flowers have some similarity to those of common nettle but not positioned so and these are red. Could it be a garden escape? The dumping of garden waste has been known round here.
