Mike's Blog - Day 195

A bit of an escapee from the ethnobotany bed for you today, Evening Primrose, Oenothera biennis. It’s no relative of primroses. If anything, it is related to fuchsia and that weed that gets everywhere, willow herb.

And here in close-up.

Its flowers close up during the day and open in the evenings, apparently quite rapidly and are quite a spectacle. I must grow some at home so I can see it. It has nectar guides on its flowers to help the moths that pollinate it, but we can’t see the guides as you need ultraviolet vision. But if you google it there are plenty of pictures on the web. Dandelions are particularly amazing. All you can see on the flower is a slightly darker yellow centre with veins radiating from it, but in UV it’s a clear “bulls eye”.

You’ll also see rose campion still flowering in the first picture. We had that on Day 123.
