Ashton Cross is a not a modern variety, but it produces heavy crops of large plump fruits, that are juicey and sweet. It has a true taste of a wild blackberry, with no bitter after taste like some of the new varieties have.
It can become quite a rampant grower, with long thorny canes.
One of the best traits is that its crop coincides with the start of the cooking apple season (end August - beginning of September). Just right for apple blackberry crumble.
We have a number of modern varieties, but we always revert back to this favourite.
