Howdy Here we have a yellow flowered trillium. Would any kind soul out there know which species it is or if its a hybrid, what could its potential parentage could be. I do know that it is fertile judging from the seedlings emerging in the last week (inside greenhouse). First pic is the trillium in question. Second pic are the seedlings. Enjoy! Hammie
Resembles T. sulcatum, a species that crosses with related ones to produce intermediates that cannot be keyed out to any particular species with certainty.
