Honey Bees in the Garden... AugustHoney Bees in the Garden... August
August 1, 2011

August is another hot month for both gardeners and honey bees. Water for plants and honey bees remains a top priority. You may also find the honey bees you encounter are more aggressive than they have been since spring. That's because they are anxious to store enough food to last the colony through the coming winter. Be careful when you bend to sniff a flower, a honey bee might be there and will think you are trying to get the nectar for yourself.

Late Thoroughwort is a common native plant in wet meadows and bottomlands from Wisconsin to New Jersey and way southward in the US. It has sharp spearhead-like leaves with long leaf stalks (petioles). Its white flower clusters bloom in September & October and are loved by bees, butterflies, and other pollinators. I saw some planted at a foundation native plant landscape of Isle a la Cache Museum in Romeoville, Illinois, where they were making good tall perennials in average, mesic soil. It is sold by some native plant nurseries.

Honey bees get nectar from this plant which produces a light amber honey.
