Are some plants better CO2 collectors than others, per unit of mass/surface area? If so, which are the better, and why?

Traveller in Time with no real answer
"There are several factors for concideration

-- surface area of leaves, more surface gives more fotosynthesis.
-- lasting of carbon matter, trees will be better for the CO2 storage then herbs.
-- surface area, several layers of leaves before remanent light hits the ground will be most productive.
-- growing speed, the faster a plant grows the sooner it will absorb CO2.

You are looking for a fast growing tree with large leaves.

May I offer you an Elder Tree ? Got some in my flower bins "

Thanks TiT

would bamboo be a good choise as it is fast growing and forms a hard woody stem ?????

"Sure, if you are in the right climate.

In my opinion it does not really matter what plants you use, each have their specialisation. Most important is to turn them into diamonds before the organic matter starts to decompose. "
