How can I tell if raspberry is primocane or floricane? Trying to figure out how to prune Whitebark Raspberry

Hello, I read up on pruning raspberries and it sounds like the approach is different depending on whether it’s primocane or floricane. I bought some native raspberries “Rubus leucodermis” that I want to try growing and the issue is - I cannot find if it’s floricane or primocane. Is there some reliable way to tell which one it is? Especially since it sounds like primocanes will still produce some reduced crop on old canes. Should I cut it and see if anything grows on the first year canes?
