Unfortunately we don't have a lot of information on this clone but it is fabulous!
As with the other double nobilis hybrids here, it's an attractive evergreen perennial with kidney shaped deep green leaves having three lobes. These are borne usually after the flowers which rise first in early spring, usually around mid march. The flowers are a real treat as they are fully double and a nice rich blue with pointed petals and no marks. The plants we offer here are vegetative divisions and will have one or two growing points.
We believe Trondgheim is a Norwegian name
