Buttonbush, bees love its blooms, is a plant that likes sunny moist areas, such as edge of swamps. I started some from seed this spring and have transplanted them in my swampy areas. When I ordered the seeds of the Buttonbush, I also got a free packet of Rose Milkweed. I did not follow the germination process, just planted them as any seeds and one plant survived. I planted it in a bank near my hive and it is now about 3 feet tall with a small flowering tassel on top. Before this I did not know there were other milkweed types. You can buy seeds and plants that honeybees like from Prairie moon nursery

I have a large Japanese Knotweed bush, looks like bamboo, which is being tended by the bees. All of these plants are blooming now in Massachusetts. I will take pictures.
