Best Blackberries and Raspberries for Oklahoma
The blackberries and raspberries that do best in Oklahoma heat, from thornless Osage, Ouachita and Caddo to fall raspberries, plus when and how to plant them.

Caddo is a thornless blackberry from the University of Arkansas breeding program, announced in 2019. It ripens early. In Arkansas trials it started a couple of days ahead of Osage, and its berries ran larger than both Osage and Ouachita, sweet, and still good-looking well after picking. No thorns on the upright canes, so picking and pruning are easy on your hands.
Caddo fruits on second-year canes. In summer, tip the new canes at about 4 feet so they branch out, and once harvest is over cut out the canes that fruited and tie up the new ones. A simple T-trellis keeps loaded canes off the ground, but you don't need one. Self-fertile, and it needs only about 300 chill hours.
Plant in full sun in well-drained soil. Hardy in zones 5 to 9. Caddo is a patented variety, and propagation is prohibited.
Caddo is part of the University of Arkansas Sweet-Ark line, bred for flavor, and its winter hardiness is about the same as Ouachita. Space plants 3 to 4 feet apart in rows 10 to 12 feet apart. If you plant Caddo with Osage and Ouachita, you'll get thornless berries from early June well into July.
Hardy down to zone 5 (-20 to -10°F)

Most orders go out via UPS with a 2-3 day transit time to most of the continental U.S. Plants are shipped dormant in late winter / early spring, packed wet to protect the root systems, and bundled by variety so they're ready to plant on arrival.
For HI and AK addresses we ship via USPS. The other major carriers either don't service these areas for live plants or charge prohibitive rates that would more than double the cost of your order. USPS gives us a reliable, affordable path to get plants to you in good condition.
If you're in HI or AK and want to use UPS or FedEx and cover the upgraded shipping cost, reach out to us immediately after placing your order with your order number. We'll send you the available options and a quote, and you can pick what works for you.
