I know this picture is not very good, but I was wondering if anyone can identify what this plant is (circled). The ladies at my job found it in the garden. I haven't seen the flowers, but they said they are a beautiful blue color. I did see, though, that they get a puff of seeds, a lot like a dandelion gets, when the petals of the flower dies off. And the heads look like a dandelion head, there are long flowing leaves on the stems, but they are hard to see with this picture. And each head has a single stem, like a dandelion has.
Thanks.
