Spekboom (Portulacaria afra) is said to sequester up 10 times the carbon of a rain forest by area.

This is largely due to a special mechanism that continues photosynthesis at night.

And it grows best in semi-arid regions.

Where people don't live or farm.

interesting, the Portulaca Oleracea is edible, I wonder if it has the same property and whether we should plant a ton of it.

Wikipedia sais it does:

"P. oleracea is one of very few plants able to utilize both CAM and C4 photosynthesis pathways, for a long time believed to be incompatible with each other despite biochemical similarities. P. oleracea will switch from C4 to CAM pathways during times of drought and there is transcription regulation and physiological evidence for C4-CAM hybrid photosynthesis during mild drought."
