Truly blue flowers
I know that many of us really love truly blue flowers, but they are elusive. Many cultivars and hybrids of familiar garden favorites are advertised and sold as "Blue" this or that.............but rarely are they a true blue color. Mostly they are some shade of lavender or violet, with a hint of blue. So you squint your eyes and they may pass for almost blue.
So, what are some of your favorites? I have hydrangea and one rosemary has light blue flowers, but at least these are actually blue. But my favorite perennial is Lithodora "Heavenly Blue". And of course the morning glory of the same name. I have succeeded in terminating the life of a Himalayan poppy, so that's no going to count for me.
I'd like to hear about any of your successes or failures.
Here is my Lithodora last year.
