I always admire these little guys when they roll out for the year. So much potential!
I had quite a bit of difficulty getting my phone to autofocus on these. I even used a second phone and found similar problems. If I focused on the roots, it would work, but if I tried to focus on the fiddlehead itself it would focus on the background. I wonder if it has something to do with the spiral shape. Went online to find out more. Came up empty on the concept of spirals as a problem for autofocus, but went down the rabbit hole on spirals in general :-)
