  • Description and Cultural Plant Tips

    Unlike the California native oaks, the Cork Oak is not susceptible to SOD, and has a fire resistant bark.  The tree is native to Southwest Europe and Northwest Africa. At one time all of the bark was harvested for making corks - after the tree was at least 20 years old. Cork Oaks can live up to 200 years.

  • Master Gardener Comments

    Takes no summer water. Has a spectacular bloom in the spring. Very hardy.  The Cork Oak is a very important tree for biodiversity in forest habitats and winter habitat for large birds.
