Star of bethlehem

Flowering at the moment, this one is actually in my garden but I've seen quite a few growing wild on various local walks too. My plant guide says it's invasive but it hasn't spread much so far.
It was warm and sunny today with very little wind, so I had another swim today with two of my usual swimming buddies. At the local beach which is walkable...Our first March swim. The water felt warmer (or less freezing) than the last swim, but that may just have been an impression.
Later back at home I did some strimming in the garden - the weeds had become too high to hang my washing out so it was pretty urgent!
