I am very dubious about the peaches claim. I was part of a long thread about peaches in North America by someone claiming I think that the Chinese brought them.
It was pointed out:
1. No peach pits in pre-Columbian archaeological sites.
2. The Spanish introduced peaches in a number of places.
And I found this (the url doesn't work now, maybe someone can look it up on the Wayback Machine:

"There are three major peach orchards within a three-mile
circumference: the Dowia Lallene, Pia Mesa and Twin Buttes, the
destination of the day trippers. This strain of peaches have a
distinctive thick green skin and are ideally suited to the high
altitude and resistant to drought. They have been traced back to
the Chinese and were brought to Zuni by the Spaniards under
Coronado in the late 1500s."
and this looks relevant:

The proponent of early peaches could not provide any oral evidence for early Navajo peaches, although he kept claiming there was some.
