This weed grows all over the place in the garden. I have always called it chickweed but today I thought I would actually look it up and all the photos of chickweed seem to have smooth leaves and white flowers where this has more jagged leaves and the few flowers that are emerging are light blue.
The stem and leaves are hairy when you look close.

Would like to know what this is for sure if anyone can help. If it is a chickweed then are there different types as well as this variety?

Cheers in advance for any info :)
