Hemp, as it grows in the wild is dioicous; it has separate male and female plant parts. However, the image of hemp that most people have is that of the female plant.
Roots:
Hemp grown from seed generally has a laterally branched tap root, like most dicotyledons. A tap root as depicted in Fig 1.
There is limited literature to support this but anecdotally, hemp will develop a fibrous root system when transplanted or grown from a cutting.
