Is this a perennial sweet pea?

[sarajane]

possibly a perennial sweet pea but I have to say never seen one that colour,

[mumofstig]

Birdsfoot trefoil?

[Mother-Hen]

I agree it's an everlasting sweat pea but I've only ever seen purple/pink ones. You are very lucky!

[Dilly Dom]

Strange the stems definitely look like sweet pea but I haven't seen one this colour either.  The one we have is pink/purple colour.

This is our second summer here - didn't notice it last year but I've just spotted two identical plants in the front garden. Could they have seeded there naturally?

[Goosegirl]

I was given one that had a yellow-brown flower. I wasn't that impressed with it so went to dig it out. Found it had roots like tubes that went very deep into the ground. It could be what you think, though the flowers do look like Bird's Foot trefoil, but I don't think it is. If you can't find out on here, try the RHS.

Hello Pony Girl

Having wracked my brains I think it is a wild flower Meadow Fetchling i.e. Lathyrus pratensis.  Its a perennial.  See if the pods are black.  Whatever it looks rather nice .... for me I love flowers but just because a weed is classed as a weed it doesn't mean that you can't like it

Dilly Dom is correct -- Meadow Vetchling it is...... a wildflower 

[sarajane]

...and a very pretty wildflower it is..

Yes the ones out the front are getting black pods!
