Term for the state of a deciduous tree during winter?

Normally I live in Australia where winters are quite mild. But right now I've been travelling in Asia and seeing all the trees which look dead but are not, due to it being winter, have got me thinking.

There must be a term for the state a tree is in that has lost all its leaves and resembles a dead tree but will "come back to life" next spring.

Like an equivalent of "hibernating"? Or "dormant"?

I don't mind an everyday word or a technical word only botanists would know. I don't care if it's a single word or a multi-word term. Nouns and adjectives are both fine too.

Dormancy is a term that applies to some plants (including trees). From wikipedia:

Dormancy is a period in an organism's life cycle when growth, development, and (in animals) physical activity are temporarily stopped. ... For example, photoperiod and decreasing temperature are used by many plants to predict the onset of winter. ... Deciduous plants lose their leaves; evergreens curtail all new growth.

Trees without leaves often are referred to as bare. To some extent, the term vernal might apply.

Edit: Instead: To some extent, the term vernalized might apply, as used in its specialized sense that means having gone dormant due to exposure to cold, and being not yet devernalized.
