Mike Rivers from Garden Web came up with the identity of the pretty but scary weed I blogged about last night. Thank you Mike! Buffalobur, Solanum rostratum. Remember you can click on the red links to be taken elsewhere for more information.
It IS a sort of pretty and very interesting plant, but this one will definitely go to the landfill today! Before it has the opportunity to spread itself any further. Rather remarkable that no one has noticed it previously, but now that I know, it won't be permitted a reappearance.
