2-gallon size potted blackberry
The Apache blackberry was released in 1999 by the University of Arkansas (a center of dedicated blackberry breeding). It has an erect, strong form at maturity, but I have noticed the young canes on 1 and 2 year old plants to be a bit trailing. It has nice, medium-large berries that get very sweet when fully ripe. Like all blackberries, best flavor of fruit occurs when it is a dull black. Apache has performed well for us, making up half of our blackberry plantings. Apache is resistant to cane anthracnose, and I have not observed any foliage disease upon it since it has been growing here (first planted in 2000). Apache is thorn-free and the fruit comes ripe in July-August here in Brown County, Indiana.
