We had a wonderful hard frost just after Christmas so I took the opportunity to get out in the morning sunshine to take a few photos!
The frost serves to outline these seed heads, making them stand out against the background but also helping to highlight the structure which is best appreciated at this time of year when the leaves and flowers have fallen.
These willowherb plants were growing in the churchyard. Each of the long, linear seed heads which cap the stem was originally filled with feathery seeds which float like a dandelion clocks when the pods split open and release them to the breeze.
Many grass seed heads are fairly transient, disappearing as winter progresses but the seed heads of cock’s foot can remain on the stem for a long time after the seeds have been released.
The spiky seed heads of burdock were slowly thawing where the sun caught them one one side whilst the frost remained clinging to the other. The hooked ends of the seedheads are prefect for catching onto the fur of passing animals which then transfer the seeds to new habitat.
The seed heads of one of the umbellifers – known commonly as the carrot family. You can see the umbel structure which gives this family its name – the flowers are borne on a cluster of stems, each of which radiate from a single point. It’s easy to see the comparison with the ribs of an umbrella in these frosted remains.
The seed heads of black knapweed. These are a member of the compositae family along with the burdock pictured above.
