There should be a curiosity you can grow in a garden pot.
There should be a curiosity that gives incentive to forage.
Bluebell can't fill those two roles alone. Either make new forage-only curiosity that's roughly equivalent to Bluebell (easy since it doesn't have to wait until reset) or replace Bluebell with something else that's equivalent to what it is now and leave Bluebell as forage-only.
