Longmont amateur plant breeder, Pete Tallman, has released the first fall bearing black raspberry recommended for the Front Range. Niwot has at least zone 5 hardiness and possibly greater.
Why is this a big deal? Now we can grow black raspberries that will fruit on first year canes in the fall. Before now the black raspberries available fruited on second year canes (summer types) and those canes were not hardy enough to reliably survive into the second year here. With Niwot, you can grow and harvest all in one growing season, cut canes to the ground in late winter and repeat.
Niwot was selected to be self-fruitful (no second variety required for pollination) and have good production of large fruit with small seeds. Fruit ripen in late August to September. Unfortunately the plant does have thorns.
There is very limited 2014 availability from Henry Field's Nursery that is selling the plant under the name 'Sweet Repeat'. Plants of Niwot won't be widely available until 2015 from Nourse Farms, Inc.
