Oak (Duir)

Duir, oak's Ogham name, is linguistically tied to the word for door — oak marked thresholds and sacred groves for the Druids, whose very name may share that root. It's the tree most struck by lightning, read across cultures as a sign of divine attention rather than misfortune, and it was central to kingship rites across Celtic Europe.

As a tree sign, this marks natural staying power — you outlast situations other people give up on, and others tend to look to you when a decision needs to actually get made. The growth edge is recognizing when a door needs opening, not just holding steady in front of it.
