General Comments:

Rarely grown, likely since it is a poisonous annual with prickles.  Invasive in parts of Asia, Africa, and Australia.

This is a personal favorite of one of the authors -- it grows and bloom early and attracts lots of insects.  The only issue is the prickles, so I wear gloves when weeding around it.  It reseeds readily so long as there is good sun and  bare ground where the seeds land.
