That isn't a flower it is a leaf stalk - have you really got it planted in a herb/strawberry planter? Could possibly be an Oxalis

i also thought it looked like a leaf from oxalis

lol, thought i'd put it there as there was a pot free and gets good sun there.
Whats a leaf stalk? lol

def oxalis,its a bulb and has pretty pink flowers,and a leafstalk is as it says a stalk with a leaf,one of many maybe,chris

I think that it is Oxalis Iron Cross.

Definitely Iron Cross, aka Oxalis deppei. They're quite late in appearing in the garden, and have coral pink flowers in the summer. Then they vanish until late spring. As Ladybug says, they usually have more than one leaf - in fact, a clump of them!

Thanks guys. I'll pop it in the ground tomorrow. Doies it like sun or shade?

Sun. I have quite a lot of them, and they come up faithfully every year...but very late on - when I think I've lost them!

lol. I'll plant it next to Bleeding heart tomorrow as i gotta feeling that the section where i have my bulbs are not working. Should've seen them coming through by now. The next section has sprouted. I planted the seeds in order they was due to spring out of the ground

mine are in a pot which I put in the greenhouse each winter, the stems are just beginning to unfurl in a sheltered part of the garden-- thet seem to do well in the pot as the leaves and the flowers are attractive
