Sand food plants
Sand food plants (Pholisma sonorae). These mushroom-shaped parasitic plants are native to the deserts of south-western USA and Mexico. They are found growing on shifting sand dunes. Their scaly stems were eaten raw or cooked by Native Americans. They contain no chlorophyll and therefore cannot produce their own food. Instead, their stems, which extend 1-2 metres below the ground, are attached to the roots of nearby host plants. This unusual plant has become endangered. It is threatened by off-road vehicles and the development of the desert. Photographed in the Algodones wilderness, California, USA

EDITORS COMMENTS
This print showcases the unique Sand food plants (Pholisma sonorae) found in the deserts of south-western USA and Mexico. These mushroom-shaped parasitic plants have a fascinating adaptation to survive in their harsh environment. Native Americans used to consume their scaly stems either raw or cooked, highlighting their importance as a source of sustenance. Unlike most plants, these sand food plants lack chlorophyll, rendering them unable to produce their own food through photosynthesis. Instead, they rely on nearby host plants by attaching their stems deep into the ground, reaching 1-2 meters below the surface. This symbiotic relationship allows them to obtain nutrients for survival. Unfortunately, this extraordinary plant species is now endangered due to various threats it faces. The development of desert areas and off-road vehicles pose significant risks to its existence. As we witness this stunning image taken in the Algodones wilderness of California, United States, we are reminded of the urgent need for conservation efforts. The intricate shadows cast by these sand food plants add depth and mystery to the photograph while emphasizing their distinctive shape and biology. It serves as a reminder that our actions can directly impact rare botanical treasures like these quintessential desert dwellers – an essential part of our natural heritage that deserves protection for future generations.
