When you would ask me to advise you three lilies for your garden of which I think are the best I would advise you to take Casa Blanca, Robina and Conca d'Or. Three lilies with large, graceful flowers that have proven to be great perennials. These pictures of Conca d'Or are shot in the garden of the Conca d'Or grower in the village of Breezand. They have been there for about 6 years he told me, planted at the same time with his Yucca, but I never realised how well they go together when I planted them is what he told me.
Conca d'Or doesn't grow much taller than 1 metre and is vert sturdy, in a large pot or planter she will also perform well. But Conca d'Or will do best in a border where she is left undisturbed, she will come back for many years.
