Looking for Snape-Centric Fic

[sanfuturo]

I remember a story wherein Severus has a house (cottage?) with a back yard full of flowers. A young Weasley girl would bring Severus a flower from Harry and Severus would send her home with a flower for Harry. It was a tragic story because she died by falling out of a tree (not in Severus' yard, however).
I'm off to search Painless_J's novel length stories list, to see if it's on there.
