A series of images, showing this beautiful seedhead as it starts to break open, until it has dispersed its seeds. I cut this twig and brought it home with me, wanting to see/photograph its development. These images were taken over a period of two days.
Gomphocarpus fruticosus is otherwise known as the bristly-fruited silkweed, a very tall plant with a much-branched stem and white flowers (which I have never seen!). It is found in damp places and gullies, cultivated for decorative purposes, and in the past the silky hairs attached to the seeds were used as down.
