This is one of those Minecraft things I ignored for way too long, then suddenly used everywhere once it clicked. "Better Botanicals: Blossom" Minecraft ResourcePack (Flowers, Spores) is simple on the surface, but it can do a lot if you like builds, traps, storage setups, or little redstone tricks. Better Botanicals: Blossom Resource Pack (1.21.8, 1.21.7, 1.21.x, 1.20.x, 1.19.4, 1.19.3, 1.19.2, 1.19.1, 1.19, 1.18.2, 1.18.1, 1.17.1, 1.16.5) brightens up the environment and adds depth to your world by changing the models and textures of flowers, spores, and more.
This is the fourth in a series of updated materials aimed mostly at increasing the little details in Minecraft's vibrant environment—making blocks or items that you may not have given much attention to previously worth constructing with or employing.
