Lindera benzoin (Spicebush)
This is about as "green bush" as you can get! But it makes up for the run of the mill green shrub look with other cool attributes. It is a native understory shrub with bright green leaves, chartreuse spring blooms and bright red fall fruit that are favored by many bird species. Host plant for the Spicebush Swallowtail butterfly. The caterpillar feeds at night and during the day hides in a leaf that they fold around them and hold shut with silk.
