Grows huge in Pacific NW including Oregon coast. Grows well in pots but size may be restricted. Potted, prefers part or light shade, unless you can keep soil moist which during hot windy days may require twice daily watering. In moist ground, wind sheltered, light shade with filtered sun, my original mother plant is 5 ft wide, 5 ft tall. Deer resistant. Keep dead fronds over plant during winter until spring fiddleheads are about 4 to 6 inches tall. Can be invasive, but that is also a matter of preference. I love and collect fern species and to me, the "volunteers" are free plants.
