Shouldn't say this but are you sure? This plant has a large tough woody structure from which these stems grow out. The plant itself must be decades old, also it has a strange smell to the extent that I thought it might be a herb. However I haven't seen a clustered everlasting that is older than say 1-2 years!
Ruth. You are right. I blew photo 2 up a lot and found that the leaves were quite wrong for even the genus Chrysocephalum. What looked like a single leaf was actually either a compound leaf or a whole lot of tiny leaves along a stem. And the flower heads are atypical. It actually looks like a colony to me rather than a single plant. I do not recognise it at all and with the strange smell i agree it might be some sort of culinary or more likely one with folk herbal properties.
