In response to the above questions: I am afraid that I do not know exactly what wildflowers I have because I got a mixed packet of seeds which did not state what the flowers were however, I do know that I have cornflowers and poppies as these have already flowered. Also, although I do dead head some of my flowers I have not done as much recently because I am either going to collect the seed to plant again next year or leave some of the flowers to go to seed so that the birds can eat the seeds and be benefitted from this. Most of my flowers only lasted between a week and a couple of weeks but I planted seeds at different times so that I get a succession of flowers through the summer, hopefully with little gaps between flowering times. Also, I grew my flowers in containers this year with general purpose peat free compost and they seem to be quite happy in this. Growing some plants in pots may help you in your garden if it gets a lot of water as they can drain easily.
In response to the questions about the sugar water I think that a way to reduce the chances of a bee drowning in the water is to place stones and pebbles in the water, preferably pebbles that allow a gentle slope into the water for the bees to land on and then walk down to a shallow bit of water. In addition you could just use a container that has no steep sides such as a plate and just fill the centre of it with water so again, the bees can land on it and move down to the shallow edges of the water.
Unfortunately I am not sure how long you should leave the water out for before replacing it but I would of thought that replacing it every few days should do.
I hope that this response has helped in some way.
