Help with Plant Identification

Hi,

Please could anyone help with identification of the plant in the picture below, I'm not sure if it is a plant or weed!? It is a low growing spreading plant only 3-5cm tall.



Thanks,
Graham.

 

Hi Graham,
That looks like Viola labradorica. A pretty but invasive perennial.

 

Hi Noisette47, many thanks for your response.

 

Certainly a Violet, but not sure it is labradorica. It looks more like Viola riviniana, the common Dog Violet. A right thug it is too!

 

It's a very pretty thug at this time of year though

 

Oh they're lovely and won't last long. Enjoy them whilst they're flowering.

 

They may not last long, but they swamp everything in our rock garden.

 

Viola labradorica, commonly known as Alpine dog violet, Alpine violet, American dog violet, dog violet, and Labrador violet,[3] is a perennial native to eastern Canada, Greenland, and the United States. The plant sold as Viola labradorica by nurseries is Viola riviniana
Looks like we're both right, Palustris Just trying to keep things simple for the OP

 

The leaves don't look like my Viola Labradorica which I have growing in my containers and pops up everywhere. I love it! It looks more like Viola odorata or sweet violet.

 

The main difference seems to be that V. labrodorica / riviniana has pointed, heart-shaped leaves and V. odorata has larger, rounded leaves.
