Englemann oaks are native to southern California and northern
Baja. Much of their original core habitat has been lost to urbanization. Their conservation status is considered vulnerable.
I bought this tree from California Botanic Garden in Claremont,
California on December 28, 2019. The gardens are beautiful and I recommend a visit to anyone interested in seeing examples of a variety of California oak species at a single location.
