We are not positive what these flowers or weeds are but the bees love them so we let them grow. It has been suggested they are called fire bush but we can't be 100% certain of that. They grow to 6' tall and last for weeks. The bee population is out there collecting pollen from them at the first hint of light and just before total dark in the evening. They are all over these flowers 14 hours a day at least and it is non stop.
Some people say the ant is the hardest working insect but I would have to say bees are the ants equal or maybe better. They work these flowers and other wild flowers all day long and I can hear them buzzing early in the morning when I can't see them due to darkness. They also like the raspberry bushes when they are first forming berries.
