Question
I have this weed that grows in cracks of roadside slabs (or between any other slabs for that matter) that I would like to get the scientific name. Also, its quite thorny at the nodes. And has some rather slight pink colouring at the 'stem'.
Answer
Dear Gerald, your plant is Alternanthera pungens (khaki joyweed), a weedy member of the Amaranthaceae (amaranth family). This plant is non-native in the northeastern United States. Best wishes.
