- "Well Georgina, a combination of my famous Rejuicing and Regerminating potions ought to do the trick. Six drops of the red Rejuicer followed by three drops of the green Regerminator will be the breath of life to a plant beyond the reach of blackmail."
- —Tilden Toots responding to a letter from Georgina Smyth on his radio programme[src]
The Regermination Potion is a potion produced by famous Herbologist Tilden Toots that forces a plant to germinate. Three drops of this potion (combined with six drops of Toots's Rejuicer) are sufficient to revive a dead Flitterbloom.
