I have them at the end of a bed, inherited them there - should move, never have liked them there.. They are invasive and grow so tall that unless you are vigilant they will fall over and cover up other plants. I think the one thing I dislike is the invasiveness.

If you decide to grow them put epsom salt around the base each spring and double your fruiting. I heard that a couple of years ago and thought well I'll try that. Worked like a charm..

Hmmm... I'm not so sure I'd recommend using them as a border. The thing is, they are always on the move so to speak. Old canes die back, and new canes are always sprouting a few feet away. I would think that for a border you'd want something more permanent. I kinda like the idea of a living border though. How about grapes on wire trellises, trained like they do to make wine? Or Blueberries? Fruit cordons?

Thanks - I did end up posting a similar question on the fruit forum, and got similar advice to keep raspberries away from other stuff due to the suckering.

I'm already plotting another location for grape vines, actually, but am now considering strawberries by the fence area, in front of hollyhocks.
