One of the things in Mrs. Jennings's description of Delaford that always catches my notice is this: "such a mulberry tree in one corner! Lord! how Charlotte and I did stuff the only time we were there!"

Just two chapters later, a mention of it is repeated in this: "The good understanding between the Colonel and Miss Dashwood seemed rather to declare that the honours of the mulberry-tree, the canal, and the yew arbour, would all be made over to her ; and Mrs. Jennings had for some time ceased to think at all of Mr. Ferrars."

To draw attention to something like the mulberry tree twice made me wonder if perhaps Jane Austen intended something by it?

In Shakespeare's 'A Midsummer Night's Dream', the play put on by the rustics is the story of Pyramus and Thisbe. They agreed to meet under a mulberry tree and both died there. Because of this tale, the mulberry tree symbolizes star-crossed lovers.
