1.12.2 version of Wild Plants by KeepMeow: https://www.planetminecraft.com/texture-pack/wild-plants/

It replaces vanilla plants and their respective names without being too intrusive:

Red Tulip >>> Broadleaf
Fern >>> Drags
Double Peonia >>> Hazard Flower
Double Fern >>> Large Fern
Dead Bush >>> Lush Palm
Jungle Sapling >>> Palm Tree
Orange Tulip >>> Small Flowers
White Tulip >>> Wild Smeller/Dracaena

It doesn't need Optifine but requires MysticalLib, being the first non mod-related Resource Pack(at least that I know of) to require Forge :P
