Hello, I just planted the hybrid, "President Rooseveldt" Rhododendron. I see the height indicated as 4 feet on the attached tag. Does this tend to be accurate or will it get taller than this? We live in Nanaimo on Vancouver Island. Thanks!
The custom in such instances is to give the 10 year height. It most certainly will grow taller than 4', and will not stop growing taller until it declines or dies.
