Could someone help me identify this plant?

It was growing next to one of my strawberry bushes and at the time it looked like a baby strawberry plant so I transplanted it. Needless to say it has, uh, morphed. It now has small yellow flowers and these odd green tubes that actually shoot tiny pellets when touched.
If anyone can tell me what it is and if I should keep it I would be grateful.

 

Welcome to GC,

I'm not able to identify your plant, but I'm sure someone more knowledgable then I am will be along soon.

 

Yea I tried to get it as clear as possible. I just googled your answer and you're right; it is Creeping Sorrel. The photo was taken about a half an hour ago. Its been flowering off and on for about 2 months.

 

Wouldn't recommend "nuturing" this plant for another hour. Dispose of now, before it takes over your garden,

OMG that stuff is a nightmare!! Get rid of ASAP!!

 

Burn the one's you have, but, imprint in your mind how they look as a shoot so you can readily identify any that spring up from the seeds that have shot out already.

 

A thug to go with Bindweed and Ground elder. Not only does it seed everywhere, the roots have tiny bulbs on them and every one will grow if left. It even survives the high composting temperatures used to produce Non Peat Multi-purpose compost.

 

Particularly annoying because most other Oxalis species are herbaceous.. but not this one.. which is evergreen. I like Oxalis as a genus, but not this particular species..

 

My two favourites :
Oxalis triagularis "Cupido"
I have plenty of these corms Oxalis "Iron Cross"- if any wants some just PM me,

The British native Oxalis acetosella can be pretty invasive too.
