While we head over to Spear and Mission to check out the authenticity of this apparent marijuana plant, please read what a tipster sent to us:

There's a giant marijuana plant that looks has been planted in front of the Walgreens at Spear and Mission. Looks like it was planted guerilla-style, and there were a couple people around with little digital cameras. Not sure what the deal is. The plant is very aromatic.

Downtown denizens, did you come across this fragrant bush during your lunch hour?
