I have to agree with John on this one. Growing up and arching down is the normal growth habit for black raspberry and definitely does not mean it is trailing. Many rubus will root at the tips regardless of whether they are trailing or not. True trailing would be a prostrate habit such has R. trivialis, R. flagellaris, or R. ursinus. I will also note that many if not most black raspberries often grow much less stiffly in their first season and will often flop over and lay on the ground and continue to grow horizontally if they've put on a lot of top growth. This usually changes in subsequent years for a variety of reasons, not the least of which is probably more vigorous cane growth on a larger root system.
I'm currently working on a project where we are evaluating over 130 populations of wild black raspberry collected from 26 states and 2 canadian provinces. Many of these were sent to us as seed by NAFEXers (Thanks!) while others were sent to us by friends and colleagues in 2006 and still others were collected on two collecting trips during the summer of 2007. In these populations there is a wide range of growth habits. Although none of them are entirely prostrate, many have a very spreading habit and once the canes get tall enough will fall over almost entirely. These could be probably classified as near-trailing or semi-erect. There are other populations with very stiff and erect canes, more so than even any of the commercial cultivars. As you can probably imagine these populations are segregating for a number of other interesting traits as well and I'm sure there will be lots of exciting news from this project in
the coming years for those with an interest in black raspberry growing or breeding.
Ernest, I'm curious to know more about the six wild populations you have from the 6 different states. Where did they originate and how did you get the seed? Was it through the NCGR?
