Product Description:

Big, dark, reddish-black fruit have sweet, tangy flavor for preserves, pies and cobblers. Rarely found in markets since the berries are fragile, but well worth growing at home, the boysenberry counts its heritage from raspberry, blackberry and Loganberry, bringing us the best of all three with its irresistible flavor, nearly seedless fruit and deep color with the added bonus of a painless harvest.

Boysenberries are 1 year old and ship late March in 3 ½ inch pots. Order early for best availability. Detailed planting information and growing instructions are included with each order and may be obtained below. Available only in the contiguous US.

Thornless Boysenberry (2) purchased

Disappointed. Very small and fragile, one (1) died, never grew, the second plant is very small, and hasn't grown any new leaves yet, but getting a tiny bit bigger. No berries this year, and hoping they are truly thornless

So sorry to hear that! The plants should arrive in a dormant state, not dead. They are 1 year old at time of shipment and won't produce any fruit until at least their second year. Please reach out, so we can help troubleshoot or figure out if we need to issue a refund. Contact our customer service (Monday-Friday 8AM-5PM Pacific Time) at either 800-626-0866 or


I purchased this item two summers ago. The first year it established well in a large pot and this year it is bursting with many many flower buds so far. Many fruits to come. Very happy with this purchase.

Overpriced for size of plant- sketchy if they will survive

First of all, quite difficult to remove from the packaging because the plants are SO small and you risk damaging them. They were like delicate twigs. They were well watered for the journey but some leaves were brown. Honestly, these plants reminded me of the hit or miss packaged vine plants from Tractor Supply that cost about 10 bucks. At this price point, I expected so much better. We'll see if these plants take. I can say that it will be a long time before they bear fruit. Not worth almost 50 bucks for 2 skimpy, itty bitty vines. Very disappointed in the quality.

Sorry to hear you are not happy with the quality of your plants. Please keep in mind these are 1-year old plants, so they will be on the smaller side, but should still grow and flourish once planted and tended to. We hope you'll enjoy many years of harvests, but we do offer a 100% guarantee on all of our products for up to 1 year from purchase. You can reach out to our customer service ( or 800-626-0866, Mon-Fri 8AM-5PM pacific time) for either a replacement (if available) or a refund.

A twig that grew

I received my plant in a 4 inch pot in 2023 spring. It was about 6 inches tall with a few leaves. I was a bit worried about planting it out in 6B conditions in April. So I kept it in a greenhouse for a couple of weeks until it grew a few more buds, then hardened it off on my deck. I was still a bit skeptical after planting it but after a while it grew very long multiple branches of canes. My only problem is it likes to sprawl. If I tie it to a post, it does a u turn back down. However it has more overall growth than a plant I got from a local farm same time. 4 stars because I have yet to taste the fruit. Fingers crossed.

Initial Instructions
After unpacking, allow the plant a few days to gradually acclimate to its full exposure. Plant your boysenberry in an area with well-drained, not soggy soil that’s enriched with humus. Initially, apply ½ cup of Territorial’s Complete Fertilizer per plant mixed into the bottom of the planting hole, backfill around the plant and water well. Boysenberries appreciate a minimum of ½ day of sun to full sun for best production.

In years to follow, apply ¼ pound of Territorial’s Complete Fertilizer per plant in the spring (before growth starts) and again in May. Maintain good weed control. If using mechanical weed control do not work soil very deep as boysenberry roots are shallow.

Boysenberries are generally vigorous growers and require support to hold up the plants. A trellis or fence at least 4-5 feet tall should provide adequate support. Our boysenberry produces fruit on the 2nd year old canes. After fruiting, the cane will die, and you can prune it back to the ground. In spring, prune the canes to about 5 feet tall to encourage lateral branching and produce more fruit. Keep the soil moist for the first year to establish the plant.

Boysenberries are self-fertile.
