Our blackberry bushes have been in full bloom for the last three weeks, with some of the earlier blooming varieties already forming small berries and the later varieties blooming in strength. As previously posted, we have Navaho, Arapaho, and Ouachita. All are thornless and were developed at the University of Arkansas.
The plants on the south side that get a fair amount of shade have done much better than the plants on the north side of the property that get significantly more sun.
Here is a photo of one of the bushes on the south side. You can see that it is loaded with blooms.
Here is another photograph of the bed of blackberries on the south side of our front yard. There are two rows of blackberry bushes interplanted with pear trees. At both ends of the bed, we have a couple of elderberry bushes. This photograph was taken shortly after a morning rain, so the plants are heavy with dew. Blackberry bushes in the landscape have a very arching characteristic. They have somewhat of a wilder look to them, so you would want to plant them in a side bed as opposed to a planting bed in front of the house.
Here is another photograph of the same bed taken in 2010, two years ago, from the opposite direction. The bed has really filled out during that period of time.
