Narrative

Are they Spanish? Hard to say, but I suspect the times militate against it being so. Safer to say they are Mexican, for California was Mexican after 1820, and I am being conservative in assigning times to these trees. They may have been chance hybrids from Baja, or even brought up from Sinaloa or Chihuahua. There are still two very large old trees from about 1820 at Fort Ross on the coast. The Russians almost certainly obtained them from Monterey or San Francisco, and possibly as seeds rather than scions. Someone I questioned about them had tried to identify them 20 or so years ago, but with no success. Those I just sent are all from single trunks, not multiples or basal shoots. I think the usual European practice was to graft the onto Quince stock (Cydonia) and there is no sign of any quinces around, although there is one at the Indians resort, 15 miles from Mission San Antonio where I got some mission grape cuttings and mission fig cuttings. We just call them Mission Figs if they are smallish and black. The quince at the Indians is atypical in that the trunks exhibit none of the verrucose usually found on Cydonia. I do hope it will be possible to ran some genetic tests on these after they have fruited and you have a better handle on identifying the varieties. Thanks for your good work. There are still 4 trees at Monterey left from the mission orchard, and as the property has changed hands, I may be able to get cuttings next year. Tom Brown 03/18/2000.
