Found at Discovery Park, Burnaby BC. Help with identifying any of them, thanks. Not sure the fern, looks different than bracken fern, not sure if that is Garry oak or not, but hopefully? The other one looks like a mugwort, and the last possibly Rosa gymnocarpa? Also maybe ninebark?
Definitely looks like Physocarpus bark. For the fern, I'd like to see the entire frond, but I lean toward Athyrium filix-femina.
It's the much more common non native English Oak. Garry Oak leaves are more deeply lobed , darker green and more glossy. Lady Fern.
