they should. as far as the game is concerned the ground is still "Meadows" even if it is high enough to get snow. Although the devs might also have added a flag that snow prevents plant growth regardless of biom. be interesting to test. I think I remember seeing some meadows right near the snow line South of my main base. Maybe if I get boared I'll check it out. :)
