New and the earliest Blackberry in trials. Obsidian is aptly named, for the glossy jet black berries positively gleam with ebony lustre! The fruits are large, conical, juicy, fleshy and have a good flavour. The growth is moderately vigorous and displays the impressive yield well for ease of picking. The total yield is both condensed and prolific. Outstanding in trials, Obsidian is a superb season extender for you to consider as part of your Blackberry planting programme, the first fruits can often be enjoyed from late June in a good summer; from the 1st of July is normal. A magnificent show variety as well as a great kitchen variety.
