Punkin Center Berry Farm offers two varieties of blackberries, Kiowa and Rosborough. Rosborough was developed by Texas A&M in 1977. It is an improvement on the classic Brazos berry, being firmer and sweeter and having smaller seeds. The Kiowa berry was developed by the University of Arkansas in 1995. It is the largest of the blackberry varieties, averaging 11 grams per berry. The Kiowa berry is a very firm berry, storing well.
I will provide you with a 5-quart bucket for your convenience while you are picking, but you need to bring your own container to take your berries home. A bucket or a big bowl is better than a plastic bag.
