Very Good tasting blackberry . I grow them with good results. The first friuts are good size. Fruit size mostly M to ms after first pick or two. Made it through the nasty cold of 2013 -2014- 2015 winters no prob. I give the productivity of Navaho in my garden a 6.5 out of 10.

We planted Navaho and Arapaho varieties at the same time (2009). Only the Navaho have done anything at all. They produce well. Last year, we added Apache and a Black Satin, but only the Apache, Arapaho, and Navaho made it through our Texas drought. This year, I am adding some Ouachita to see how this works out, but so far Navaho have been good producers and have grown and spread vigorously while the other varieties have struggled. It is a little early to tell with all except the Arapaho and Navaho, but if you want a thornless blackberry that seems able to withstand Texas heat and drought conditions, Navaho is the one.

First ever thornless blackberry introduced in 1988. Since I'm in z9a, this variety may not do well in my area but I see it at the local garden centers every year. I decided to give it a try and planted in an area that gets a little bit of afternoon shade.

Planted this plant, Rubus occidentalis 'Navaho" PP6679, in the spring of 2006, I live near Grapevine Texas and it survived a very hot summer w/ drought. This year, 2007, it has put out new canes, covered the old canes with green growth and is loaded with flower buds, I am excited, I found another 'Navaho" this month and planted it with the older plant. Today I found the "Arapaho" variety and planted it this evening. I will upload a photo when the flowers are blooming.

Excellent quality mid-summer blackberries are the product of this upright 6-8' thornless, self-fruitful variety; prune canes (that have fruited) to the ground in fall. Hardy to zone 5.
