They don't really need any specific lighting, but for them to fully bloom in the pot it still requires a blizzard. Some of them won't grow because that's just how the dice rolls or there's a limit to how much can grow in a limited space. It doesn't have to be in a snow biome either. Here's a pic of my shiverthorn farm. I planted all of those at the same time and some never even got to 2nd stage. Just be patient and wait for a blizzard.
