Black raspberry season stretches from late July to early August. We have VERY FEW black raspberries this year as the canes were chewed by porcupines so PLEASE CALL AHEAD if you are coming specifically for these berries.
They are NOT THE SAME as wild blackberries, they are earlier, larger, jucier and sweeter. Their thorns are also much larger, so be careful and wear tough clothing if you plan to pick them. While Black Raspberry ice cream and soda are some of my favorites, most people just nosh on handfuls of them.
We have 4 rows of Jewel black raspberries & are experimenting with some in high hoop houses.
