Flowers

I decided to try and plant flowers on my patio this summer. Hopefully to cover up my view of the construction they're doing next door.
I don't know anything about gardening; my only experience is planting flowers during volunteer activities. I'm pretty sure I planted everything too close together. I'm considering it survival of the fittest, whichever plants get biggest get all the water. I planted Begonias (white and pink), Impatiens (red) and Bugleweed (blue flowers).
