Ok....bit of a minefield with cuttings. Now's the time you should be taking soft or greenwood cuttings. These are taken from the new, soft shoots of plants like Fuchsia and Penstemon. I would put these in a pot and then in a polythene bag and keep warm but out of direct sun.....if you've got an electric propagator, a bit of gentle bottom heat is ideal.
As you get into mid summer....July to End of August, the wood on the plants tends to get a bit tougher. This is when the bulk of shrub cuttings are taken and these are called semi ripe cuttings. Put them in a pot then in a warmish area out of the sun....a coldframe is ideal.
Finally, when certain plants have lost their leaves (Forsythia, dogwood, Philadelphus, Ribes), take 8" long cuttings at any time between November and March. You can put the cuttings in pots or just stick them in the ground. I had a bit of a bare area in a winter garden I created at work so I just took a load of mixed dogwood cuttings and put them where I wanted them to grow. They don't need any winter protection but don't like sitting in waterlogged soil so lots of grit is the order of the day.
Get yourself a decent book on propagation....there's plenty out there and it should tell you what plants are suitable what type of cutting and when to take them.
