The first is https://www.nexusmods.com/skyrim/mods/74223/? . Here are couple of screenshots: I also use https://www.nexusmods.com/skyrim/mods/79391/? . Whilst this was created for Unbelievable Grass 2 (UBG2), the generic edits are still effective. As seen below. (pls note all screenshots are using Verdant but I am currently using UBG2 atm)
