Friso or Silkroad as it also is called grows very well here.
I believe it has good hardiness both in Sweden and Denmark. Like many American bred lilies it is usually slightly later to emerge than the Dutch bred ones, so therefore it is less susceptible to frost damage.
Pic from last year:
It's my tallest lily. Here blooming above the large Miscanthus grasses. It probably topped out last year at around 9 feet. It was growing too closely together so I have moved them further apart now. The huge inflorescence needs plenty of space. I'm thinking about planting crown imperials between them to get som height early in the season, but then I need a cultivar that doesn't increase too quickly as I won't be able to dig them easily. Perhaps Striped Beauty will work as it is a slow increaser.
