Thistle-like plant, not commonly cultivated. I'm giving it a try to see what it's like. Just seedlings for now – the photo here shows a first-year plant in early July. I haven't found a good reference for its hardiness, but suspect it may not be up to our zone 6 winters. Certainly, the plants I started in 2013 did not return in 2014, so I'm going to hedge my bets and grow at least one plant on in a trough in our garage, which is probably equivalent to a zone 8 exposure.
