Q.Milkweed Has Not Produced Flowers. Why?
I have 4 milkweed plants (I believe swamp milkweed, definitely not the butterfly weed.) They are tall, have started branching out, but no buds even visible. These are in their first year. It is autumn now, can I cut them down and hope they produce flowers next year?
