Many of those simply have flowers that are finished for this year as Dave says. The lilies for example, and foxgloves. Remove the spent heads if you don't want plants to go to seed, and to tidy the plants. Letting plants go to seed weakens them too, especially when they're young plants, as they put their energy into making seed instead of maturing.
There aren't really any plants that flower continuously throughout the year, apart from annuals - and that's not what you have. There are exceptions like the phlox which flower for a long period in the right conditions, and it can be very useful as a foil for other things, but you need to pick a few more plants to give succession. Some small shrubs will help with that too, and give some structure when the perennials are dormant over winter.
I've also just noticed that your soil doesn't seem to come anywhere near the top of the beds - there's a lot of timber showing. That doesn't help light get to plants. The soil level should be much higher, and it might be because the compost will have settled and compacted. It would have been batter to mix the soil and compost rather than layer it, and you then need to let it all settle before planting. Weather will play a part, and you usually need to top up raised beds a couple of times to allow for that settling.
