Rubus ursinus × R. idaeus

Boysenberry, probably created by Rudolph Boysen and certainly popularized by Knott's Berry Farm, is a complex cross between the European raspberry, European blackberry, American dewberry, and loganberry. A distinctly tart, juicy treat, these large, red-black berries mature at up to 2 inch long. The harvest of delicious, aromatic fruit continues to ripen for up to two months. Try eating them fresh with cream, mixing them into a smoothie, or baking them into a spectacular pie - exceptional.

Trellising the trailing, vigorous canes on a 2-wire system works well; the first year primocates down low, and the 2nd year floricanes up higher where they will be easy to harvest from.

Cold Hardy to USDA Zone: 6

Mature Height: 6' or more

Definitely Boysen

I planted mine in the ground back in late July and now 3 months later it's just about filled in the trellis space I gave it. I'm attaching a photo of it from a month ago and since then it's grown to the top and beyond. From its growth habit and leaf characteristics it acts and looks like a Boysen to me. My particular plant had more basal branch growth from when I planted it and it's only slightly less vigorous than some Rudy's Original Boysens I have planted next to it in a large planter, but everything else looks and acts similarly. With Boysens, or any trailing blackberry, you really want to avoid pruning if at all possible and just keep routing the canes anywhere you have space. If you run out of space just start looping them in a spiral. Pruning will not produce additional yield but it will make the canes want to fork off in 2 or even 3 different directions. Additionally you really want to go with a thorny Boysen over a thornless as the latter are not genetically thornless but chimerically thornless which reduces vigor and yield. I personally don't mind thorns so I always default to "thorny" plants.

3 boysenberry plants

All 3 arrived healthy. I planted them right away in my newly prepared bed for them. It has been a few weeks now and they are growing and thriving. They even have a few blossoms already!
Thank you for such beautiful plants!

Boysenberry lives!

I was unsure about this one and the N TX winters but its thriving. A few flowers and a few new shoots . I want it to spread so thats a nice feature.

An excellent start

The boysen arrived in excellent condition. I am planting it inside a 27 gallon storage container(with lots of holes for drainage). It is inside a fence, to keep the deer away from it. It is doing well, going to sleep for the winter.
