About plant names...

Coast live oak is native to the west coast of North America.

Identification: These evergreens reach 20-82' (6-25 m), with trunks up to 4' (1.2 m) around, and may live up to 250 years. Trunks are short and the crowns are wide. Bark is smooth and gray-brown when the tree is young, becoming darker and somewhat furrowed later. Leaves are dark green, thick, glossy, oval in shape, alternate, edged with sharp fibers. They remind me a little of holly leaves. They are ¾-2½" (2-7 cm) × ⅜-1½" (1-4 cm). Male flowers are catkins 1¾-4" (5-10 cm) long. Female flowers are ⅛" (5 mm) long, in clusters of one to three, barely noticeable. Acorns are 1-1½" (2.5-3.8 cm) long and ⅜-½" (1-1.5 cm) wide, conical in shape. Acorn production is not consistent.
