My Food And Flowers 
I have heard of this flower, but have never seen it – thx
You are welcome! Yes, it is not as common as it should be.
🙂
These grow wild in the woods where I live although they are not common. Several years ago I planted the berries in humus-rich soil under aspen and red maple trees. There are now several small plants in that spot.
It is a nice native perennial, I hope they will grow more in the future!
I’ve never seen the plant before it really is blue! A really useful herb too 😀
