It is located here in Oregon in the Willamette Valley, where iris farms abound and lily hybridizing got its US jumpstart back in the 1940s at the Oregon Bulb Farms.
It was invitation only, for members of the Hardy Plant Society of Oregon Lily Study Group (the former Pacific Northwest Lily Society). I have to say though that they weren't carding anybody
.
So the climate here is dry summers (no rain) and wet fall, winter and spring. I noted that Mak had drip lines running along his rows of lilies. I expect he has better drainage than me as I am close to the river and have heavy clay, while his place is atop a ridge.
