Is this tiny flower Cow Parsley or something else?

[DreamKitty]

So this tiny white flower has been growing in my garden, I picked it up. The flowers were in clusters, very close together, the stalks were of medium length and had around 4 petals each with a yellow centre. 2 big petals and then the other two were smaller. The smell of the flowers is musky & sweet. Im wondering if it is either, cow parsely, yarrow, poisonous hemlock or something completly different. They look so alike, im confused. But anyway, I see it in lots of people's gardens.

Here is a photo, I resized the pic so it might look a bit weird lol.

It is Candytuft. It comes in many colours and is a perennial. Not poisonous to my knowledge.....http://www.growsonyou.com/shop/product/3991

Thanks Davie, feels so good now that I know . I had been searching this flower for ages, I knew that it couldn't be cow parsley because the leaf description is different. I thought it can't be yarrow either as it has 5 petals instead of 4. I was actually on the verge of eating it out of frustration lol but after doing some further googling, I found that it is inedible and has no medical use other. Oh well, the flowers that adorable to look at.

Never play with your carrots when cow parsley is in flower, or your MIL is staying.

Iberis, good, I got it right. Cow parsley is more likely to be seen in ditches and fields in the countryside and less so in people's gardens in London!
