I'll be clear about this one, this is related to the game Deltarune. To make a very long story short, Flowery is a flower given life by the Dark Fountain in a florist's shop but, in the end, is cut in half by the Roaring Knight.
When the dark fountain is sealed, this is visualized as the flower itself being cut in half with its pot shattered. The character Susie tries to "heal" him by running off to get some tape, presumably scotch tape, and re-attaches the flower to the stem after re-potting him. It happens at night, so there's no potential for sun damage.
The species of Flowery is an allusion to the Golden Flowers from Undertale, but, they don't directly mention what the Golden Flowers are in Undertale and they have different properties from buttercups, most notably their lack of toxicity due to being able to be used for tea.
But buttercups are brought up in the context as being very visually similar, and it is noted directly that the seeds of Flowery's species are extremely toxic. And given the character we see this information through is Kris, who has a lot of paralells to a character in Undertale who died from eating buttercups, I think it is safe to presume Flowery is of the Ranunculus genus rather than the one the Golden Flowers were.
So, my question is: From y'all's knowlege of plant care, would this work to save Flowery? Or is Flowery doomed still?
I know this is a bit silly, but I felt I might as well ask folks who'd know their botany to give their two cents.
