After 2 years (they're biennial), and upon flowering, I tried to cross-pollinate the two- and succeeded! "Tragopogon mirus" was the result (the cross has been previously recognized as occurring in North America, but not where their native ranges overlap in Europe), and has traits of both parent species (and is polyploidy)! |
