Monarch Watch has Common Milkweed listed as the number one milkweed for my area. I already have swamp milkweed and was thinking of adding another variety. However, I have read that Common Milkweed is very quick to spread and get out of control. I have also read the opinion that Common Milkweed does not belong in the home garden. I would love to hear from those of you that grow the common variety. Love it? Hate it? Also has anyone planted it in a large pot and put it in the ground to control the spread. Very curious about this interesting plant.
