Propagating Black Eyed Susan?
One thing I like to do with Black Eyed Susans. I dont dead head the flowers in fall, I let the birds come and eat the seeds. Its nice to see the birds and they seem to spread the seeds better than if I throw the dead flowers back into the bed.
Butterfly Bush Not Leaving Out?
Try cutting the bush down to the ground and see if that does the trick. I cut mine back every spring and then it takes off, by fall its about 5 feet tall again.
