The name suggests that this is a cultivar that was bred by Kees van Duivenvoorde. He was going to name all his new cultivars a city name.
This is an evergreen Agapanthus with beautiful full blue flowers. This one was in our collection and because we thought it was so special, we decided to grow it further.
