You have the P. bifurcatum, perhaps the var. 'Netherlands'. You have done a good job growing the stag,
@AlyssaBlue. You'll see every shade of green possible on my website. I grow lots of stags. The darker green the fronds are (generally speaking) the lower the light levels. My staghorns grown in really bright light have much lighter green fronds than those grown in mostly shade. Your plant may well be 1.5-2 years old.
By the way, 90% of all the staghorns I have grown will be mounted. That allows them to grow as they do in nature, where they are generally attached to trees.
