The first Thornless Blackberries were selected from more than 10,000 seedlings. Fruit is sweet and tasty, ripening late. Here, growing in a dry area, they are somewhat undersized.
Look closely at the stems. Though very sweet, the fruit is small and seedy, lacking adequate irrigation. These are possibly a variety called 'Sebastopol' which bears fruit from September to November, a little later than the ones in Santa Rosa, named 'Santa Rosa'. Four different Thornless Blackberries were introduced. These here are the first of their type and they still flower and fruit abundantly.
