  • Question

    Another Rubus from my yard in Massachusetts. I transplanted it to its current location because it was in the way. When I moved it, I noticed the stems were growing roots where they bent down and touched the ground. Is that behavior typical of the genus or only found in a few species? Based on the contrast in stem color, maybe Rubus occidentalis?

    Answer

    Dear jfc, yes, this is most likely Rubus occidentalis. Two features should be present if correct. (1) the leaves will be whitened by hairs on the lower surface and (2) there will be small but firm prickles on the stalks to the flowers (which are absent in Rubus idaeus). Best wishes.
