Hello!

I saw this movie roughly 5 or 7 years ago, it was about a mother who was pressumably insane because she claimed to see fairies when she ate the flowers of a tree in the backyard of her home (mansion?), later the mother dies and a young man comes to investigate her death (i dont remember if he was a doctor). One of the daughters dies as well when she tried to eat one of the flowers but she fell from the tree instead, the young man was intrigued so he ated one and start seeing this weird, sort-of green fairies.

The movie was all in sepia tone but the fairies, english spoken and set in the 1900s or earlier, hope someone knows about it 🙂
