Trillium Traits and Identificaton
USDA websites lists 39 species of Trillium in the US and Canada. Though T. grandiflorium is the default everyone seems to think of when we talk about Trilliums it doesn't exactly have a wide range. In fact none of the species have a wide range at all, it's just grandiflorum is the easiest to identify. I won't get into all the details because the flower needs to be described with scientific terms, but here are a few I used to ID this species.
Let's use the picture above to start out. I'm assuming the ones photoed there are the same species, after all they were labeled as such (I just forgot which one). The flower varies somewhat but remember, one divided this year while the bigger one focused more on making a taller stem.
Trillium grandiflorum, though it is known as the standard white trillium has been found in lots of colors. Some turn pink after pollination. One type was found to have a pink flower as soon as it opens. There is a doubled flowering one with no reproductive parts at all and has only spread by cloning itself. There is a hybrid with T. luteum that has a yellow flower. And I've even seen a red flowering one on the internet. God only knows what the other 48 species have to offer in diversity.
Four leaf Trilliums are good luck after all, and have been known to occur.
