Best variety

I live in western Minnesota. please recommend the best variety for my area that would give me crop all at once for picking over a couple of weeks. thank you.

Doug says the people to check with for a best variety of raspberry are the local hort extension folks (for all regions of the U.S.) that specialize in fruit production. They'll have lists that work for your specific region.

One of the other problems here is that there are different tastes and berry-condition issues (I used to grow them commercially - or at least I tried) to make a single recommendation. For example, 'Latham' is a great old plant but tends to get viral problems. 'Boyne' is better and more vigorous but the berry is hard and to my tastebuds, more like cardboard than 'Latham'. But 'Latham' crumbles very quickly.

You can see the problem. Find the berry that does best for your area according to your local hort folks - then use it as your main berry - and experiment with others.

Yes, it means you have to sort out some stuff for yourself here (sorry) but specific varieties for all parts of North America is not something I keep track of (hard enough doing it for my own region) :-)
