No need to be offended Chomp. They are just trying to help you. I actually just purchased my first Drosera Adelae at Lowes 2 days ago. This is the first time I have seen one there. Usually they get in Drosera Capensis. They have one sitting there right now. I had one I bought from Lowes a few years back that over ran my terrarium when it went to seed.
Those care sheets on those little terrariums, usuallly are just generic. The one on my new dew also said full sun, but the general growing instructions for Adelae are shade, to partial sun. They can grow quite large, so if you do not have a terrarium, it will quickly over grow the cube it came in. They can reach 8" in diameter.
Funny story came with my sundew........When I purchased it the woman who rang me out, was looking at the cube funny and the plant inside, after she looked some more she finally asked................. does the tongue really come up out of it like that? (Questioning the sticker they use to seal the cube shut.) I gave a chuckle and politely said no.
Good luck with your new dew!
