Can Salmonberry thrive and produce fruit if planted in a large pot?

In theory yes, if kept watered and shaded

I am looking for Pacific Rose verity of Salmonberry NOT Olympic Double. What one do you supply? Ray Delbury Sussex County NJ USA 8-12-23

Our Salmonberries are not improved and resemble the wild ones in the Pacific Northwest. If anything they are likely closer to the Olymic Double than the Pacific Rose.

Does this berry need a trellis or something to tie it to to control it?

No, Salmonberry is pretty much free standing.

You list salmonberry as growing in USDA zones 4-9, but it is native to the NW and all your commenters seem to be in cooler climates. Will this survive in central Alabama, zone 8a? Our challenge for northern plants is not the mild winter but the long, hot, humid summers which encourage diseases. Summer here is basically April through early to mid October. Raspberries, currants, and gooseberries will not survive here.

USDA Zones refer only to the lowest average winter temperature a plant can survive at. It does not reference summer temperatures or other climate features. Salmonberries grow here in the PNW in full shade and, as you correctly presume, will be unlikely to thrive in hotter, longer, and more humid summers.

How wide of a thicket can you expect in its native pnw?

6 feet wide per crown on average. It takes time and they need full shade.

would this grow well under a pine?

Yes! Salmonberry loves acidic soils and full shade.

Do salmonberries have thorns?

Absolutley yes! Smaller, greener, and fewer, but just as sharp.

Do salmonberries have thorns?

Definately. Smaller, greener, and fewer, but they are thorns.
