Since water was scarce and had to be hand-pumped, decorative plantings were minimal. Fruit trees and vegetables were grown as a source of food. The Leonis Adobe grounds has a variety of fruit trees and shrubs, including apricots, plums, figs, pomegranates, and blackberries.
Also grown on the property is a less common fruit, the quince. The quince is part of the rose family and is the sole member of the genus, Cydonia. The quince is a fragrant, hard, yellowish fruit resembling a pear. It is essentially inedible for humans as a raw fruit but is ideal when cooked, commonly used for jellies, preserves, and candy.
