Blackberry Cane or Plant

Wild brambles spread themselves around by tip rooting - the stems (or you call them Canes) drop to the ground and root wherever they land. That's how bramble thickets grow and, when you need to clear them, you have to pull up every rooted tip.
Some of the other long stem fruits also do this - don't ask me which as they lost their names years ago.
I don't grow cultivated blackberries - just pick the wild ones that grow in the garden.
