One is Euphorbia, two is an Azalea and three I am not sure

I agree but its difficult to tell on the third need a closer pic of the leaf? is it Forsythia or Weigela

Three looks like Forsythia. Did it have bright yellow flowers a few weeks ago KM? A close-up of the bark on the twigs might help. If it's rough with paler, yellowish spots it's Forsythia.

Forsythia, definitely I would say.

Forsythia which needs a good prune...

I would guess the first one is euphorbia robbiae -a great plant for very dry shade where nothing else will grow, but beware - even there it spreads like fury. And also be careful if you break a stem - it has a white milky latex which can be very irritating to the skin and if you get any on your hands be very careful not to touch your eyes. Don't let it put you off though - I've grown it for years with no problems.

Apologies for the delay in responding, i have had a problem with my computer. I have had it confirmed by a family friend that the third picture is forsythia, so thanks for all the suggestions. Bamboo, youa re right, it definately does need a good trim, it is on my list of things to do. Im mid weeding at the moment. Steragram - thanks for the advice on the euphorbia, i will keep it in mind and have just moved some of it to a very shady area of my garden, il keep you posted on the progress!! Thanks again to all.
