Where it grows
Neogaerrhinum filipes is native to the sandy deserts of the southwestern United States and northern Mexico. Its flowering period is from March to May. The plants, due to being hidden by low bushes, are hard to spot because its stem is usually covered by the leaves and twigs of other plant species. Locations where the species has been documented include slopes in the Grand Canyon, within the Mohave Desert and within the Sonoran Desert. It can be found at an elevation of up to 1650 meters.
