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 blooms early and attracts lots of insects. The only issue is the prickles, so do wear gloves when weeding around it. It reseeds readily so long as there is good sun and bare ground where the seeds land.
