Speculation, Fact and Fiction

There's an oak tree locally that's out of synch with all the others. Last autumn it stayed obstinately leafy and green while all the rest turned to autumn colours.

It was still flaunting flame-coloured branches when all the rest had been stripped to bare twigs by the winds and rain. Including the ones in the very same stand of trees.

Now it's spring and the oaks are greening all over hereabouts. Except this one. Well, it's showing leaves but markedly more slowly than the rest.

Is it a transplant from another world, like the apple tree in The Magician's Nephew?

Do its roots reach into some parallel universe where time runs slightly differently to here?

Does it have a terminally lazy dryad who's never quite gets caught up with her To Do List?

Or one who's into subtle statements of individualism?

**addendum** Nope, not a pin oak (as per comment thread suggestion), not as far as I can tell. So we're back to the dryad hypothesis.

Scatty and inclined to do her own thing? There must be a short story in there somewhere. Possibly tucked into a pocket of one of the coats...
