California Coast Live Oak
A gorgeous evergreen oak, the California Coast Live Oak grows west of the Central Valley from Mendocino County all the way down to Baja California. Trees take on various forms, from scrubby multi-stemmed shrubs to stately 70 foot tall spreading trees. In our northern climates they often take the latter and with great haste and minimal water to boot! Though trees from warmer provenance have proven successful here we think our seedlings collected from the northern part of its range will provide even more cold hardiness for an already exceptional street tree. Water for the first couple summers to get trees established and then let it fend for itself. Acorns can be eaten once the tannins are leached out and are beloved by wildlife.
