Quercus lobata can
attain a height and spread of nearly 100 feet. The deeply lobed
leaves, large acorns and cobbled bark are prime characteristics of the
Valley Oak. Quercus lobata can be found on the valley floor where it
has access to groundwater. Quercus lobata produces its acorns from
late Summer into Fall. The Valley Oak is more threatened than
the other species as the flat area in most valleys where it resides is so
frequently used for agriculture and houses. The new foliage of the
Valley Oak is a pale dusty pink. Quercus lobata is one of the most
stately of our California native trees. The root zone of the Valley
Oak extends well beyond the reach of its branches. Care should be
taken when planting or constructing under Quercus lobata to avoid damaging
the root system. On the hottest days oaks suck up so much water that
they can destabilize large branches which in turn come crashing down.
