This weed has taken over! It grows to over a foot tall with thorns. The leaves grow three to a branch. It spreads from shoots that grow up out of the roots. Many many roots – that are about 5 or 6 inches below the surface.

    Black berry.
    Good luck digging this native out.

    While the blackberry is a valuable native fruiting plant with medicinal properties, those thorns and running root system makes it a thug in a garden setting.

    It has never had a berry – and I have been digging it up. It’s tough.

    Can you repost with pix of the thorns and roots?

    You get flowers and fruit on second year canes.

    When keeping all the berry plants dug, you won’t see the berries…. But you sure do see a lot of re-growth of the plants.

    Try leaving a plant in an out of the way location, and in the Spring, you will see the blooms, followed by berries around June.

    Will post photos of roots and thorns in a day or so when I can. Can I put them here or do I start again?

    This is growing in my pasture also. Does anyone know the name? It is not blackberry.
