Dianavan, your blue creeper sounds like germander speedwell sometimes known as Birds Eye speedwell, and it grows in grassy meadows all over the northern hemisphere - although this gives just the UK as it's a site for English nature.

They're lovely flowers and I've not seen any for years.. not enough unshaved lawns here in London.

A little rain over the weekend and yesterday (it WAS a Bank Holiday after all) has helped - although most of it was over Kent and Sussex rather than London. It's as windy as anything today so I think I'll be looking rather than planting this afternoon!
