I'm not sure what these flowers are, but Google image search tells me they are probably alliums. I didn't think they were going to bloom this year, as I came home from vacation on June 5 last year and had missed their blooms altogether. They didn't even look like they were planning to produce buds on June 5 this year, but they're making up for lost time now.

This picture reminds me of a crumbling castle wall holding back a hoarde of angry peasants whilst the bourgeoise cower inside, aware that the end is nigh.
