I love finding and getting pictures of flowers in the wild. Finding cool flowers in the wild means more to me than a huge manicured garden, because this happened all on its own, and its up to you to discover it. Also flowers are one of my best indicators on both identifying a wild edible and also as markers for me to know where we are in the season. Since I take so many pictures each year, and many times of the same flowering plants, I can compare the dates on a particular flower between years to see if we are having an early or late spring, etc. When I am having problems identifying a particular plant, if I can catch it while it is flowering, I can almost always positively identify it, then the next year I should know it much better even before it flowers for the year.
The trillium has wonderful flowers as well as being a wild edible, the leaves when it first comes up can be used as a cooked salad green, however by the time the trillium flowers the leaves are too bitter to consume. I missed trying the trillium this year because I was not totally sure of my identification of it (and I had mistaken a Jack-In-The-Pulpit as a trillium anyways which would have been a shocking mistake!). From my reading you do not want to pick trilliums as an edible most times anyways as they are not that abundant, so you should only pick them if there is a large amount in the area already.
