Rotation randomization with Hair (Particles)? Limited to one axis?

I’m scattering some trees across a landscape, and using Hair to instance the trees.

(I’m most likely going to switch to Geometry Nodes to do this, so if you have a good GN/trees tute, I’m all ears.)

It looks like rotational randomization is limited to one axis. Is this correct? I can get the trees to “lean”, but not rotate.
