A lot of changes in the garden take place slowly, sometimes without being noticed until they’re complete. But frost, and the way it changes to semi-frozen beads before melting into glistening droplets has been a very visible feature here recently.
The top photograph shows the process of the thaw caught mid-way. There’s still an icy ridge of frost crystals running along the seed head, but below it the sun has melted the rest. It was the first time that I’ve photographed these Miscanthus seed heads – the frost added something extra to give interest to the image. (And they do tend to blow around in any breeze, so very still weather is needed for a decent photo.)

You can see the seed head at its most frost-covered in the image above. It didn’t stay that way for long because the Miscanthus is growing in the area that gets the first sun of the morning. Any frost on this grass melts away very quickly. It’s only because we had several days of very low temperatures that there was this build-up of frost crystals.
Those frost crystals soon thawed in the sun and became the icy little drops that are seen in the photo below. But this wasn’t the only change taking place as I photographed the Miscanthus. I was surprised to see how quickly the hairs on the individual grass seeds fluffed out in the sun. (You can see how dry and airy-looking they’ve become in a very short space of time.)
I suppose the seeds must be programmed to wait until there’s some warmth before opening out their hairs and getting ready to fly away in the wind. Later on, when it was cooler, I noticed that they had closed up again. Since that morning, I’ve seen the fluffiness appear in the sunshine and disappear as the hairs close when it’s cold. Perhaps this is a way of protecting the seed-hairs in bad weather, so that they don’t get bedraggled, and allowing them to stay dry enough to let the seeds float away when the time is right. It’s an intriguing little change that had gone unnoticed here before.
