Forget-Me-Not (Myosotis)
I’m always forgetting what these are called.
Well, not really. They are members of the genus Myosotis and are very pretty little flowers, most effective in large drifts. I don’t know which species these are (there are about 300) but I believe they may be Myosotis sylvatica, a European variety commonly known as the wood forget-me-not. They are short-lived herbaceous perennials and where they are growing in our garden sort of shifts from year to year, as new seedlings grow and old plants die, but we still have a little area where they seem to be happy.
