Could someone help me identify this ravishing little plant which I noticed was blooming in one of my flowerbeds and which I can't remember having planted at all last year. Quite a nice surprise but very intriguing too. I saw it on google images but with no data so as to put a name on it. May be our encyclopaedic Ceridwen would have an idea? I've added an extra pic showing the leaves. Thanks in advance blippers!
