Quercus emoryi is slow-growing in the wild, where it often occurs on rocky ground with little or no topsoil, and is clearly tolerant of hot, dry conditions, as its grey, holly-like leaves suggest. In North America it has proved to be extremely hardy, remaining evergreen in Zone 6–7 conditions (Melendrez 2000).

For Quercus emoryi, the male inflorescence is a catkin which is initially compact and stiff, but eventually unfolds to become longer and hang loosely from the branch. Female flowers are very small and petal-less, emerging from the growing stem at the point where a new leaf is attached.
