A cool flower
The garden feels like it's at that moment when everything is on the cusp of exploding into bloom. Right now this is one of the cooler flowers I have blooming. It's one that should really be viewed up close to truly appreciate its unique shape, and the dark purply blue looks awesome next to a chartreuse hosta.
Its name is centaurea montana, but in my garden, it's just known as perennial bachelor button, which is what my mom calls it, and it came from her garden, so that's good enough for me!
