Scientifically referred to as Crotalaria cunninghamii, it belongs to the legume family that also includes the edible chickpea and alfalfa. It's a perennial shrub, by definition, and is native to the sandy dunes of inland northern Australia. Interestingly enough, there are no hummingbirds down under, yet this plant thrives in this specific part of the world. Needless to say, people on the Reddit post were in absolute awe of the plant and began sharing it elsewhere making it go pretty viral.
