Common Name:  Blue oak
Family:  Fagaceae
Author:  Hook.&Arn.

Mature Height:  12   Mature Width:

Habitat:  Dry soils in valleys, rolling hills and lower mountain slopes to 1350 metres[62, 82], often forming extensive stands[229].

Propagation Notes: Seed - it quickly loses viability if it is allowed to dry out. It can be stored moist and cool overwinter but is best sown as soon as it is ripe in an outdoor seed bed, though it must be protected from mice, squirrels etc. Small quantities of seed can be sown in deep pots in a cold frame. Plants produce a deep taproot and need to be planted out into their permanent positions as soon as possible, in fact seed sown in situ will produce the best trees[11]. Trees should not be left in a nursery bed for more than 2 growing seasons without being moved or they will transplant very badly.
