left unchecked this plant spreads fast. two summers ago there was a patch of blackberries running along a four wheeler trail in my backyard and last summer this trail was closed and so the blackberries immediately took over.it is a great plant to have around though. i enjoy picking blackberries in the summer.

I am growing a plant of rubus ursinus in Vancouver, B.C. I grow it to hybridize with the Loganberry, Tayberry and others. I collected seeds last year and will be planting them. The plant makes trailing growth and needs trellising. If they are collected from the wild then be advised that this species has both male and female plants! You must choose a female or you will get no fruit. So find one that is bearing fruit and tip-root it for next year's plant. The berries are small and are delicious for jam, etc. Quite a few plants are necessary if you want to have a reasonable yield. I would suggest at least four plants, spaced about four feet apart. If you plant them right next to a loganberry, raspberry or boysenberry then they will be fertilized. Otherwise you must grow male plants... read more

Easy to grow from ofshoots (from layering or stolons). Bears prolifically on second year wood. Requires litle atention but can be invasive. Very thorny. Rapid spring growth. Can form impenetrable bramble over time (prunable to hedge shpe).

The famous Loganberry is a cross of California Wild Blackberry and a rasberry. The wild berry is better!
