X-22 Botanical Garden

 is a location in the northwest of the Big Empty in the Fallout: New Vegas add-on Old World Blues.

Layout
A long metal staircase in this area leads to an upper area guarded by spore plants and spore carriers (similar to the ones found in Vault 22 and Zion Canyon), along with the unique spore carrier, Patient Zero. The canyons are buffeted with red gems that give off light during the night.

Notable loot

 * Sink Project: Biological Research Station holotape in the upper area guarded by spore carriers and Patient Zero, near a hot plate and a duffle bag containing some ammunition among other junk.
 * A seed package with various dried seeds in the second level of the upper area guarded by spore carriers.
 * Broc flower, mutant cave fungus, and xander root grow nearby.

Appearances
This location appears only in the Fallout: New Vegas add-on Old World Blues.

Bugs

 * When on the highest peak of the facility (the area with the fountain), heading north, you will encounter a pipe that connects to another plot of land. Despite appearing to be solid, the pipe becomes static halfway through and you fall through.
