Hi all, sorry to bother you guys again.

I was wondering if any of you guys could possibly shed light on the
hardiness of a couple of plants. I was looking at rudbeckia occidentalis
"green wizard" and a Cardoon in various places online and off. Depending on
where you seem to be shopping, both of these have been marked as hardy
perenniels, tender perenniels, half hardy-perenniels, or even half hardy
annuals, I was wondering if anyone here had any first hand knowledge of
these plants as it's now getting a tad confusing?
