Hi,

I am confused as to what zone I live in. I live in Gresham, Oregon.
Also, I really like Purple fountain grass, and was wondering if there are any perennial varieties. How should I winter it over since I keep it in a pot?

Thank you.

It looks like you are zone 8B.

Hi and welcome. The US Dept. of Agriculture has maps showing your hardiness zones here:

However, just your zone designation really doesn't tell you an awful lot about what you can and can't grow where you are. It's so much more complex than that.

Here's a thread from last month where we had an in-depth discussion on this topic:
The thread "Zones - what am I missing?" in Ask a Question forum

You don't need to leave this site to find your zone:

Thats funny, I live in nw Houston and I am in zone 8b, chuckl. Sometimes zone 9, and sometimes 8a- durn microclimates....

Hi, MontanaSky! Welcome to NGA.

I think you're in Sunset Zone 6. Scroll half-way down this page:

Does this sound close?

ZONE 6: The Willamette and Columbia River Valleys
"Zone 6 is still a maritime climate,with a long growing season (from 155 days at Cottage Grove to 280 days in Portland neighborhoods) and 40 to 55 inches of annual precipitation most places. ... "

"Warm summers and chilly winters make the Willamette Valley one of the West’s best-known growing areas for berries, hazelnuts, roses, flowering fruit trees, and broadleafed evergreens."

"The Willamette Valley’s hills and small mountain ranges create many microclimates."

I like the Sunset Zones. They try to make zones small enough that, within that zone, you can mostly predict what will or won;t thrive, and not just based on "Are our winters cold enough to kill them?"
