Quercus greggii La Siberica strain

Quercus greggii La Siberica strain

A fantastic and unique oak from a Sean Hogan seed collection! From high elevation in Mexico, this oak has been fairly widely planted around Portland.  We could use a few thousand more though! This tree has proven itself cold hardy here and likely hardy in slightly colder climates. Like many high elevation Southwest and Mexican species, this oak loves our climate! It grows as as smaller shrubby oak in its native habitat. Here in our richer soils, it forms a small tree. Lovely wooly texture on the leaves. This is an evergreen oak, that drops its leaves in April before flushing out new ones.
