Tidestromia suffruticosa, the shrubby honeysweet,[2] is a perennial plant in the family Amaranthaceae of the southwestern United States and northeastern Mexican deserts.

It has one of the highest rates of photosynthesis ever recorded.

[3] It flowers from April to December.

[3] It can survive very high temperatures, growing successfully in extreme environments such as Death Valley,[4] and the genetic basis for this is being studied with a view to making hardier crop plants to better cope with climate change.
