...can you tell me the outcome of when you donated the blackberry plant? I donated mine also, but it all went so fast...
I can tell by your spoiler that you and scalad are talking about different things.
You gave the curator a Legendary Black Orchid. I know because that is the action that causes the curator to walk you out to a spot on the south side.
Scalad had a normal, albeit rare, flower called a Blackberry Ananas. You probably aren't going to see one of those for a while. However, it is just a flower, and went into the Museum as an exhibit.
I'm going to address your question: what was the outcome of giving the flower you had to the curator?
You gave Ronald the Legendary Black Orchid and he walked you out to a spot near a big rock and the South River. He had you dig up a dirt mound, and you found a paper, which I refer to below as "the thing I mentioned". Either you successfully gave it to him or it's still in your inventory. See the next spoiler-marked bits to tell what to do next.
I think you were successful. If so, this is what happened:
Ronald read the note. It moves the story line along but does not require any further action from you. There are some things that don't happen in the game until this sub-plot is finished. I will tell you what the note said in a PM if you are curious.
On the other hand, if you were not successful, then you still have the thing I mentioned in your inventory. You need to give it to the curator. Here is how you can tell for sure:
Walk north to the River, near the old bridge. It doesn't need to be finished. Look across the river to the trees. Do you see something colorful in one of the trees? That doesn't happen until you've finished the Legendary Black Orchid sub plot. There are other things that don't happen but this is a good marker. If you have the colorful thing, PM me and I will tell you what Ronald the curator said.
