The photos are definitely of blackberries. I'm not sure why they would throw in the raspberry and mulberry names as well, unless it is a listing for an assortment, or they just send whichever of the three they have on hand! But none of the three are commonly grown from seed if you want specific traits (large size, etc). There are numerous named varieties to be propagated vegetatively for that. Lastly, of course thornless would only refer to the blackberries, since mulberry trees never have thorns, and all raspberries do. Hope this helps!

Thanks. It helps. Have you ever seen or heard of a mulberry tree with extra large fruits? Ours produce lots of fruit, but aren't especially large.

And if those are blackberries in the photo with the hand, what variety to you suppose they might be? They look worth the trouble to pick.

Kiowa produces largest blackberry I've seen - comparable to those in the photo, but mine are not typically that long - but they've never seen any fertilizer, either. I can pick a gallon of Kiowa berries in about 10 minutes... definitely worth the trouble.

Don't know if Kiowa is zone 4b hardy, though - I've been growing them for 10+ yrs here in southern KY, but polar vortex of 2014 killed mine back to the snowline, and it looks like the winter just past killed floricanes back to the ground.

Kiowa is not even zone 5 hardy . No matter that they list it as zone 5 .

I'm with you on that, jerry... solid z6 here, and it's taken two big hits in the past 10 years or so... but still worth growing here.

To answer the question about large-fruited mulberries... Many of the common named varieties were selected for their larger than average fruit size, and some of the varieties for milder climates, such as Pakistan are impressive (up to 4 inches long). Tehama, Giant White, and a few others I can't recall should be quite beefy. Biggest mulberry for colder zones would probably be Illinois Everbearing. These can be longer than your typical blackberry, but not as thick.

Apart from all other considerations, unless you are breeding them, you don't grow blackberries from seed. Sounds like yet another Chinese eBay scam to me.

Thanks to all. I see what you mean. Does anyone know who carries the Illinois Everbearing mulberry? If my Chinese seed sprouts anything, I'll post.

If you do a Google image search for those pictures you get hundreds of hits. The scammers are just using a stock picture off the web to part you and your money.

For Illinois Everbearing try Stark Bros or England Nursery . I got scion wood for it From Cliff England this year .

My guess is that they are describing/selling boysenberry.
