Canada Goldenrod and Late Goldenrod usually stand in the same stand and are often confused in the field: the Canada Goldenrod has hairy stems, the Late Goldenrod a smooth, frosted stem, and it starts earlier. Both form dense stands on fallow ground, along railway embankments and on gravel areas, and this area is what makes up the yield. The nectar supply is rated rich, the pollen supply moderate, the pollen orange-yellow and easy to recognise on the pollen loads. The catch lies in the timing: from late August, what is brought in no longer goes into the honey super but into the brood nest and thus into the winter feed. Anyone in goldenrod country who feeds early should check the feed chamber before wintering, otherwise more goldenrod flow than expected ends up in the colony alongside the fondant. From a nature conservation standpoint both species are unwelcome because they form closed stands and displace native species; establishing them deliberately as bee forage is explicitly discouraged, as it violates the Federal Nature Conservation Act.
