Hm...we just bought one from Turnbull down in Collins (?) NY. I imagine they must work out ok, or they wouldn't sell them (hopefully anyway, lol).

They are not hardy. I tried for about five years and quit. If you search this forum there are threads on hardy trailing blackberries; Boysenberry seems to be the best choice for colder places like yours.

They still can be grown if you take the canes down and cover them with a thick cover for the winter. I did that for a few years but then got tired of all the work.

The fact that a local nursery sells something doesn't mean much, local nurseries tend to know almost nothing about fruit.

I'm going to try and grow them here too, last night it got down to 28 degrees and the plant is actively growing, no damage on leaves, although some of my tropical plants got hit bad. Anyway an encouraging sign. If they can take the winter, we will see, but the plant seems pretty hardy to me so far. I know that 28 degrees is not extremely cold, but when active leaves shows no damage that tells you a lot about it's ability to withstand cold. Fruitnut's plants didn't fair well in these temps.

Drew, the hardiness of leaves is not closely tied to dormant hardiness. If you don't cover them this winter and you get zone 6 lows, they are very likely to die - even 10F is cold for them and you are 20 degrees below that by zone.

The original thorny Logan is probably more hardy but it seems to have disappeared.

I found a supplier in the U.K.
