A cowslip (Caladenia flava), a very common flower that is pretty much always the first orchid out where present. The other Caladenia spp. are generally bigger, showier and present flowers higher up (around waist level) and I love all of them, but I have a soft spot for this gorgeous, rich yellow flower.
It’s lovely. Did it come up on it’s own or did you plant it there?
It’s a wildflower. Came up in natural (although disturbed) bushland on campus.
