I have grown Lilium maritimum outdoors near Duvall, WA, just east of Seattle. We're mostly zone 8, with occasional cold down just slightly below 10 F. They have survived and persisted for about five years in raised beds on a sloping terrain, with underlying sandy or gravelly loam soil that drains well. They tend to be rather small plants and remain so, which puts them somewhat at risk of being overtaken by nearby plants in a competitve garden bed, so they are probably best grown in their own container or bed.
