The Phenomenal Berry I got from him this spring have been absolutely pushing out growth for their first year here - and very healthy so far (alongside my Ranuiberry). Unfortunately, they’re probably a bit tender for the winters here, but they’ll be moved to a double wrapped high tunnel greenhouse to curb winter damage. Excited to see how they turn out. He’s pretty much the only one I’ve seen sell the plants - I wonder what his history is with them? I know they’re a Burbank creation from CA, and he grows them in San Fran.

I’m planning to test whether I have Lincoln Logan or the thornless chimera (I got my plant from Raintree) - some of you may have already done this. The thornless Logan chimera has the thornless mutation in the L1 outer epidermal layer, but not in L2 or L3 (the internal layers). Roots derive from the internal thorny layers, so if you grow root cuttings and they are thorny, you have the chimera. If your root cuttings are thornless, you likely have Lincoln Logan. Has anyone already done this?

I haven’t but I have grown seedlings from mine, all of which have been thorny. I’ve been considering the root cutting method because I’d like to have these plants but thorny to try and get the deer off of them.
Mine are from Stark Bros.

I’m weird in that I actually prefer thorny plants over thornless. Part of it has to do with some purist/originalist thing, of course, but it’s also a beneficial annoyance to pests and when training nursery tape binds to them easier with less sliding around, plus you can use the leaves as velcro if you’re doing the wreath style. I usually train with my bare hands and occasionally get poked, but nothing major. Atleast it’s not buckthorn or cactus.

Hi, It is my understanding that Lincon Logan has not been released to the public. It has been used in breeding. The Columbia series all have Lincon Logan as the sourse of thornlessness. You may get a thornless Logan type by crossing Chimeral or thorny Logan with Columbia Giant etc.

I think Black Jewel is the Euro name of our Jewel Black…
If someone wants to grow just one i think Bristol is the one..at least from what ive grown and seen..
Bristol offers up to and maybe more than 1000 blossoms per plant.
This Fall or whenever you do your pruning and training.. try laying the canes horizontally as some train fruit tree limbs laterally. The result is stunning compared to the standard practice of vertical canes.
That video is a good representaion of canes that arent nearly as productive as they could be.. missing out on many thousands of fruit per planting. Cane length and orientation are incredible factors in fruiting.. as with fruit trees and trailing blackberries and laterals on erect and semi erect varieties.

Victory as noted fruits here from June until frost. Futher proof that canes are not ‘spent’ until they actually are. Second week of September here. .. there has been fruit of various stages of ripeness since June on these plants. I know of no other plant that does this. Maybe it makes it an Everbearing Blackberry?

I’ve decided that, sometime this winter, with enough time to stratify, I’m going to order seeds of a about a dozen varieties of Rubus from Sheffield’s, because I like the multinational genetics, and then trial them in my project area.
Should make for some interesting specimens and the opportunity for some novel breeding work, too.

My 6x Blackberry Raspberry hybrid fruit is reaching 10g in weight. I do not like the round shape,so I am hoping that the 4x Blackberry Raspberry hybrids will have a longer fruit shape, similar to Rubus glaucus.

Very impressive size! What kind of blackberry did you use in the cross?

Orange rust? This is Caroline. Quick interest search sats red raspberries are immune…whats going on here?
Doesn’t look like orange rust. Looks like run of the mill leaf rust or raspberry yellow rust. Neither are terminal.

Hi, I used a primocane, thornless blackberry, that was a chance seedling from Driscol’s ‘Elvira’ Blackberry.

I’m guessing a tetraploid? Any idea what species it may have been bred from?
Primocane and thornless in a chance seedling is pretty impressive, good basis for a hybrid for sure.
Hi, Yes, it is a tetraploid. I suspect they used Arkansas genetics to get both Thornless and primocane fruiting in one plant. Since both are recessive, all of the seedlings will be thornless and have some primocane fruiting. I was lucky, the seedling I have is very self fertile and has a strong primocane fruiting habit. I had 2 other seedlings but their flavour was weak and they both had big problems with fertility. They were both culled.

Very cool, especially if it was a U of Ark pedigree. I had harbored worries that erect, busy, large flowered blackberry types like the species the U of Ark blackberries were bred from might not be compatible with raspberries. The trailing dewberries that all the previous crosses had been made with seem like they’d be less dramatic of a wide cross. But sounds like there’s a good chance I’ve no reason to worry.

I know this is a shot in the dark but any guess as to what this may be ? Dual cropping. Primocane ripens about 10 days after heritage. Pretty firm, very strong raspberry flavor, a bit less sweet than heritage. Canes have small thorns.
Hi, I had no problem with the crosses. The semi erect habit went through to the 6x hybrid.
