The pink ones are all over now (March). I think of them as wild gerania but have never come up with anything more specific. The white ones which I think of as wild alyssum is I think Hymenolobus procumbens, but I've never had that confirmed. Oron? Anyone? (I can take more detailed photos)

Until Oron corrects me  I'd say that the geranium is Geranium robertianum, and the white flower Lobularia maritima (syn. Alyssum maritimum, A. odoratum, Draba maritima).

Alisdair, the Blamey/Grey-Wilson illustration shows the G. robertianum with reddish leaves of a different shape. The ones I am talking about are bright green and shallowly lobed with a  round rather than elongated shape. See photo below.They also describe it as having a rather unpleasant smell, which again is not the case.  Also B/G-W say the L. maritima has whitish or silver leaves which is not true of the ones here. This book has been my trusty reference/field guide from back when I knew nobody interested or knowledgeble. Is it time to stop trusting?

The geranium leaves certainly aren't robertianum - thanks for photographing one. They look more like G. rotundifolium. The "silver" look of the Lobularia leaves is actually a covering of fairly dense hairs on leaves that are basically green - if your plants have hairless leaves, then I guess they can't be Lobularias. A close-up of the flower would help: Arabis hirsuta?

Here is the whole plant--not a great photo I'm afraid but it will serve its purpose.:

I would suggest Geranium molle and Capsella bursa-pastoris.

Thanks, Oron!

Thanks, Oron.
