Growing up, my grandparents had a shrub like plant which they called Apple Ringy. If it's any help, this would be in the Lothian area of Scotland.
I'd like to plant this in my garden, but when I google the name I get Artemisia maritima as the real name - but the plant I remember was more green-grey rather than grey-grey IYSWIM. It had a lovely apple/lemon/herby smell which you could sort of smell as it grew - but like lavender, you could release the fragrance by rubbing the fronds.
Anyone have any clue what I'm on about? TIA!
