I explained this in the my previous post.
"babies are very variegated. But when planted, as the leaves mature, they turn fully green, sometimes with just a slight tint of gold, where they were once white."
So if you see a plant with dark green leaves, and the spikes with the babies coming out are very, very variegated. This is the best clue you have for the Hawaiian Spider Plant. None others that I am aware of do that. Generally if the plant is variegated, the babies are variegated. If the plant has all green leaves, the babies have all green leaves.
