I encountered this attractive little flower on an early morning walk. It’s very, very tiny; the flowers were probably about 3 to 4 mm across. What was unusual about it is that consistently, some flowers were yellow and some blue—on the same plant. That’s fairly unusual, so I looked it up.
It turns out that this is Myosotis discolor, the Changing forget-me-not (also may be called the blue-and-yellow forget me not, among other things). The flowers start yellow but change to blue as they get older. It’s listed as an Exotic in Canada; in other words, it was introduced, escaped, and has naturalized. But it’s not considered a pest.
Which is happy for the plant, and for us. It’s a pretty little thing.
