Orange milkwort (Polygala lutea) is 1-2 foot tall biennial also known as “Candy Root.” Though it should not to be confused with the species that exists more in the southeast, Polygala nana, which is sometimes considered a subspecies, other times as its own species. The plant itself produces a lot of milky sap, which is not what you should be eating, instead you should eat the roots, which taste like candy. That said, while some descriptions refer to it as wintergreen flavor, others are that it tastes like licorice, which not something everyone really considers to be candy, so beware.
Orange milkwort is a plant that loves wet sandy acidic soils, common for places like pine barren bogs, which means it’s not great for growing in a garden unless one lives in a wet sandy area. That is also why it is endangered in New York and Extirpated in Pennsylvania.
Unfortunately, there is little information about it as a host plant for insects, but as a flower it does support pollinators. It is also eaten by generalist herbivores.
