I have both of these hibiscus,the kopper king is in a pot and I have acetosella in a pot and in the ground.Neither one has shown signs of life as yet.My other perennial hibiscus have signs of life thus far.Are the kopper king and acetosella later to come up than other hibiscus's?All of these hibiscus were left outside during the winter.I'm a hour away from Fla so our winter was mild.Thanks.Debbie
