The low-growing canopy of wild ginger's (Asarum canadense) leaves conceals a bizarre flower. Deep red, with three petals, the plant blooms at ground level, where it is pollinated by ants, beetles, and flies. Ants later consume the protein-rich covering around the plant's seeds, called “elaiosomes,” and discard the seeds elsewhere, helping the plant to spread. Wild ginger prefers shady areas and rich soils, making it a great native plant option for a home gardener in the eastern United States seeking groundcover in a less exposed area. Though the name suggests it may be tasty, consumption is not advised—the plant does contain several toxic compounds.
