Description of Obsidian Plants & Fruit:
An early cropping variety with mightily big, beautifully glossy fruit, the Obsidian blackberry tops it off by being one of the heaviest croppers around.
Be patient - the fruit will aquire their best flavour only when they have turned totally black.

Growing Obsidian Blackberry Plants:
Because it's such a big cropper with large fruit, we do recommend a sunny spot to get the most out of Obsidian.

Background Information on Obsidian Blackberry Bushes:
An American breed, created in 1993-1995 by the US Department of Agriculture's Agricultural Research Service (USDA-ARS to its friends).
It's parents are from a series of blackberries known simply as ORUS - it probably won't help much to know that it was ORUS 828-43 and ORUS 1122-1 that gave rise to Obsidian (a.k.a. ORUS 1369-3).
The man behind the project was Dr Chad Finn.
