There are lots of annuals that you can buy as plug plants or sow from seed that like sun and are showy and colourful. But the answer to summer sun is not to let the soil or compost dry out. I live in Dordogne where it can get very hot in summer and I grow a lot of flowers in pots, petunias, rudbeckias, salvias, snapdragons, verbena, diascia, French marigolds, pelargoniums etc, but I water them every day or two.
In the flower beds Dahlias, agastache, perennial salvias, gaillardias and penstemons are bright and showy and flower over some time.
I don't know about a dog poo wormery, not appealing for me!
