Herb Robert question

[Muddypaws]

Has anyone seen Herb Robert with white flowers? None of my ID books give white flowers as a possibility. I saw this recently, and I am certain it is Herb Robert.

And here it is next to some regular pink variety:

There were several of the white plants in the locality. Those with white flowers were exclusively white, no mix of white and pink on the same plant. I have never seen the white flowered variety at any other location.
Have I inadvertantly discovered a new subspecies?

Neat
Certainly looks like it........never seen a white one before either
It's a weed in my garden, pretty though and easily removed, but it gets huge given the chance.

Bound to be one of the botanists along to say yeah or nay

cheers,
Toddy

I believe there is occasionally a mutation.

Just checked my hamlyn id book and it says you do see white flowers rarely.

Thanks Listenclear - my book (Collins Complete Flower Guide by David Streeter et al) which I thought was the most comprehensive is obviously not as good as all that!
Shame I won't get any credit for discovering a rarity.

Maybe not, but we know it can happen now
That's a result

cheers,

Yeah for sure and I wouldn't have read all the info in my book if I hadn't been looking for that information.
I often find that you need to read a few different texts to get a better idea of stuff - one book is never enough (or that's my excuse anyway).
Still, it is a rare find so good show
