lol@video - nice misdirection
For vegitation you can install Skyrim Flora Overhaul... It replaces all vegitation and makes it much more dense (read description page - you need to change SkyrimPrefs for it as well)... I am not sure about the Thristle texture, or how it looks in SFO.
But if you're interested in making Skyrim look a lot better... here's a small guide from me
This is in Installation order ... when it asks to Overwrite in NMM, overwrite.

**Project Parallax for Windhelm might cause CTD. If you get CTD traveling to Windhelm, uninstall it.
Read the mod pages before you go and install.... Load order is important, tho most of these are texture replacers, so not too many .esp/.esm files to take care off. Some are manual installations... I'd suggest you download them [manual installations], extract them and repack them...
When repacking make sure the Skyrim folder structure is followed starting with Data
So, when you unpack a manual mod which extracts as
Subfolders: Full, Lite, Performance
Make sure you pack the version you like as Data\..etc and zip it ... (in the example above you would zip the Data folder you want in Subsubfolders, naming it whatever the mod name is) then in NMM Mods tab click on "Add" -> "From File" and select the archive you just created... this way you can have that manual mod managed by NMM and you can install - reinstall it, without having to worry about file overwrites and so on, as you have to with manual installations.
Hope this helps cheers
PS. you do need a decent system for this...
PSS. Please do not go on the internet for skyrim.ini changes/tweaks which generally suggests to change the uGridsToLoad value (other tweaks are fine) as it can cause issues when you mod your game because your system (no matter how badass) will crumble and die. uGridsToLoad should be left alone, and should be set to 5 (default). The mods above (Enhanced distant terrain, Distant decal fix, High quality Lods) take care of distant terrain details a lot better than what uGrids can achieve.
