As the season fades from memory, all our milkweed is dormant EXCEPT the African one! In a pot on the fairly exposed eastern patio, and next to the house on the north side, it's defiantly green. This one is sometimes called Asclepias fruticosa (though it has several other scientific names, and I wish whomever would make up their minds). It's the one with round, fuzzy green pods and the picturesque nicknames like Family Jewels or Tennis Balls.
