Thank you for the comments folks.
Roshni; take photos of things you find interesting and you will probably get interesting pictures.
Rob; tell yourself that they are not weeds, they are native Scottish wildflowers. A weed is just a plant in the wrong place, a Scottish wildflower belongs in Scotland, so it is not a weed. The local birds and insects prefer native plants to some fancy hybrid that belongs in Kenya too. On top of that, they are easier to look after and they are free!
