Echinacea purpurea, bought as a pink variety, but clearly it is not! It was labelled "Ruby Star", but I think the dark-red-stemmed plant next to it is the real "Ruby Star".

Monarda didyma, started from seed 2 years ago. I haven't had any mildew problems here, as is common for this plant. It creeps slowly, spreading to form a large bunch, but is not really invasive in my garden. It is very attractive to bees and butterflies.
Thalictrum rochebruneanum "Lavender Mist" (a meadow rue). A visitor to the garden commented that this perennial looks more like a tree. It certainly is taller than me! 
Papaver somniferum seed heads with purple Cleome spinosa in the background.
