Copied pasted from discord:

• in biomeswevegone, the item form of the flower patch is very green
• why are several flowers not tagged as flowers? like many flowers that have visual flowers on them are not tagged in block form
• why is horseweed and winter succulent tagged a flower?
• just to be clear about flowers:
  minecraft:small_flowers for small single block normal flowers like vanilla's dandelions or tulips
  minecraft:tall_flowers for 2 block high flowers like rose bush
  minecraft:flowers for any special flowers that doesnt fit in others like your cactus flower or petals or flowering lily or witch hazel blossom

Side note, I dont think biomeswevegone:eroded_borealis actually spawns. Teleported a ton of times and did search command
