With the kind permission of Discovery1, I present you:
A collection of Discovery1's flora replacers made into a not-a-replacer version that works with BSAs!

To use one not-a-replacer, simply download the ESP and one of the many BSAs. Put both into your Data folder and activate the ESP.
Since this is not-a-replacer, you can switch this on and off with the ESP, or simply choose one of the other BSAs to test which one looks better in your game.

What ever you currently use, vanilla or one other replacer by Discovery1 or someone else, will not be overwritten.
If you deactivate this ESP, your current replacer or vanilla is still there, unchanged! This means you have two replacers at the same time.

Those who use my Jungle for Everyone should already know how well this works.<-With this you can even have three replacers at the same time.

Loadorder: It is best to load this after any landscape changing mod like UL and as low as possible anyway. It is not important, but still highly suggested.

Just in case you want to change or update something. All textures should be in the folder: data/textures/plants/grassreplacer
The folder "grassreplacer" has to be created first.
