South Yorkshire,
United Kingdom 
our garden was planted up about 3 years ago when we moved into a new house. We have a n area with a seat which has gravel underfoot. Around this and at various levels we have (amongst others) the following plants: honeysuckle, lavatera, lobelia, bamboo, nasturtium etc. on the gravelled area there is now a carpet of a small leaved plant/weed which we cannot identify. The leaf is small and roundish and so far no flowers. It's threatening to take over. Do not think it is nasturtium.

Annie, Nasturtiums are annuals with rather large leaves and pretty bright coloured flowers, you can eat both leaf and flower in salads and they taste peppery, it would be good if you could take a photo of this plant, that would help ID. it.

Are they celandines? They have a small roundish leaf and my garden has loads of them, but I would have thought you would have seen the flowers by now.

Too early for the nasturtiums yet - need a photo really.

Do you have a picture for identification?
