We can always handwave that Eustace sent him some! So to answer the question, I'M KEEPING IT SIMPLE LOL and just have it where that when the flowers fall off, they can remain fresh and then can be dried or pressed however to be used. But if the dogs are in a good mood or just will it to be, the flowers can turn into candies instead. The pups create a more gummy like candy but the mom can create rock crystal candies.

The better their mood, the sweeter the taste! And the worse their mood, the bitter it is.
