I agree with B3 about those being red hot pokers. You can plants lots of different types of bulbs right now for colour in the autumn. I'd suggest planting in clumps rather than scattering them about. Is there a garden centre near by? Failing that a Wilkos or Mossisons? They all have the seasonal bulbs in stock at the moment.
If I were you I'd dig over your borders and add some rotted manure to get them going. Do lots of reading and research about the plants and colours you like. Ask yourself questions like do you want plants that come year after year, or would you rather plant annuals every year? Think about heights. Do you want any climbers? Do you want scent? Do you like certain colour combinations? Do you like structure? Do you like the movement of ornamental grass?
Have a walk about and see what does well in gardens near by.
Test your soil to see what you have. You can get little kits for a couple of pounds at garden centres.
I planted two borders up at my new house three years ago. I wish I'd taken a step back like you are doing. I just bought everything I liked and plonked it in without proper thought. They're a bit of a mess now, so I'll be digging it all out in autum and re-arranging / re-newIng. Autumn is a good time to plant as it is when a lot of things a dormant.
Good luck with it. What a great project! Keep us posted.
