From the CO2Science archive: Eragrostis curvula (Schrad.) Nees has sometimes been referred to as an invasive species. But it’s invasive only in the sort of way that pampered tourists are, since it was imported from South Africa and then planted by hand across the US to take advantage of its qualities as a versatile ground cover suitable for erosion control. It’s also known as Weeping Lovegrass, a pronunciation far easier to love and another example of a plant that would be a good name for a rock band. And in 2001 and 2011 a total of 7 experiments showed that an additional 300 ppm CO2 boosted its growth by an average of 48.1%. So this Lovegrass isn’t Weeping over your CO2.
