The intended solution is to get the Sprout Clover, which becomes obtainable as an item artifact once you sell the Sapling Sword. It's an Overworld item, like the Force Orb, so it will carry over into Colosso. If you can't find it go to the item lady where you would normally buy items like Clarity Clovers, but choose "artifacts".
Glad you're enjoying the mod. This does open my eyes to the fact that Sprout is not nearly as accessible as I intended to be and will see what I can do to alleviate that once version 2 is released.
