Joshua Tree comments from elsewhere

  • The tree is pollinated by the yucca moth which is attracted by the flowers scent. The larvae then survive by eating the seeds. This seems self defeating but then there is little food in the desert.
  • Joshua Trees have a deep and extensive root system, with roots reaching up to 36 ft from the fibrous trunk
