| Distribution | Scattered across most of the state, but with large gaps. No doubt many other populations have been seen but not considered as escapes (i.e., considered to have been deliberated planted, almost always in secretive, out-of-the-way places).
Native of Asia; in N.A. Que. to Ont. and ND, south to NC and OK. | |
| Abundance | Rare as an escape from cultivation. Populations are often well-hidden, so that this species is under-collected. | |
| Habitat | Crop fields, roadside ditch, cutover woods, creek floodplain, campus shrubbery, small openings in forests. | |
| Phenology | Flowering and fruiting June-October. | |
| Identification | Marijuana is familiar to most people as a tall to very tall, rangey herbaceous plant with leaves deeply palmately divided into 3-9 serrate, tapered leaflets. Be careful if and when you stumble onto a plant or a population; you don't want to be spotted by the person who planted them. Certainly if you see a sizable number of plants, you should contact authorities -- assuming you were on public or otherwise protected private property. | |
