Help identifying these shrubs / plants

I moved into a new house several months ago, I am yet to work out what some of the shrubs are in my garden and how to care for them, any help would be greatly appreciated!

 

2nd one is a Hebe and the 3rd is Hypericum, probably Hidcote

 

perfect thank you, any idea what kind of hebe? I googled it and there are quite a few and I can’t find any that look like my one!

 

Patty's Purple Hebe...maybe.

 

1st one is a Nandina domesatica

 

Thank you, is it not meant to look like mine then with long leggy branches? Should the leaves be closer to the ground?
The problem I have is the house was an ex show home that was empty for a year before we moved in which meant no one tended to the garden and I haven’t a clue what most of it is and how aggressively I need to prune things and when!

 

The best time to prune nandina is in winter, when it is dormant. As far as how, the books recommend cutting about a quarter of the stems down to the ground. Then cut a third of the total stem height off one out of every four remaining stems.
