Excellent response to planting on moist clay above a pond in a partially shaded location on Camano Island.

Most of the human population here is concentrated in USDA 8, perhaps you are located there as well. Search internet for "washington hardiness map" or similar phrases to see.

There are a couple sites that I've found that put my zip code in zone 7. It seems easier to go with the widely accepted zone 8 though.

Zip code zone finders put me in USDA 7 also. I am well within USDA 8. Probably the finders are based on the same misunderstanding/ignoring of what average annual minimum temperature means as causes people to put themselves in the wrong zone.

I planted a 'green screen' last fall and another one recently. I have the standard F. Robusta too, which has been in the ground at least 4 years. I like it better than the green screen, because of the narrower leaves.

Last falls plant is shooting now, as is the older one. They put out a lot of shoots after a year or 2. Last year I counted over 20 on my older plant. Appropriately named! I plan on putting in more of them.

The one on Camano was planted as the typical plant. Don't recall it coming with a cultivar name.
