What fruit trees and plants did the spanish bring to California?
Virtually all of the common fruit trees were imported by the Spanish - with apples, oranges and lemons quite prevalent. Each mission had an orchard and extensive plantings of grapes, to produce wine. The primary crops grown in the field were wheat, barley, corn, peas, lentils and beans. While some plantings came from Spain most reached California from New Spain (current day Mexico) which a Spanish possession for a couple centuries at the time the missions were founded in what the Spanish called Alta California.
