Like all other Mojave Wasteland plants, ripe banana yucca plants found in the wasteland will eventually regrow after being picked by the player, making them an unlimited supply of free food. Picking one plant yields two fruits.
There are four plants growing in Westside, in the northeast corner (near the entrance to the Northern Cistern). There are another 3 growing due west (still within Westside), halfway between Klamath Bob's, and Miguel's. Another 6 grow here as well, but they are owned and must be stolen.
Honest Hearts A large amount of the fruit can be found growing in Zion Canyon.
