I have 7 hardy hibiscus that I planted 2 years ago from bareroots. Its end of May and they are just starting to show new stems. More over they just have 2-3 stems and just grew 2-3 feet last year. They are on the north side of the house near the foundation. They do get 3-4 hours of morning sunlight. Are these guys just slow to start off or they are distressed? I am not sure why they are not full grown yet.
