I have found some too and thought, "How pretty and I bet it is nitrogen-fixing." Thanks to this post, I looked it up at Dave's and here is a picture of it's rampant growth. The caption was, "Give it an inch....."

Very nice photos :o) I'm not good at identification with no books for reference but yes, #3 Garlic Mustard HAS TO GO... it is an EXTREMELY prolific alien invasive weed very difficult to control once it gets a foothold. This time of year it is easy to see from it's upright growth and flowers atop. Pull them from the lowest point possible. There is a "nub" at the base of the stem and if you get your fingers just below that nub the whole plant will come out roots and all. These things sew zillions of seeds so it's best to get them out now before the flowers go to seed. #4 & #27 are Jacks. Young jacks DO look like trilliums. #15 looks like very young jacks. #9 & #12 do look like Arrowood viburnum to me as well. #10 looked like false solomon's seal to me (thought I saw a flower bud at the distal end of the stalk. Did they flower underneath? #11 looks like a "cornus" (dogwood) species 14 is definitely real sololmon's seal by the flowers falling under the stalk. #19 and #22 both appear to be Sensitive Fern #26 Looks like plants I have in my window "Hawkweed". Mine are orange but there is also yellow. I like these very much but they aren't native here. I have them planted in the window boxes of my shed, in window planters on my house and in my front garden. #33. Wild violets as everyone else has said. Good luck with your identifications :o) Barb

I got my Castilleja from a nursery. It came with the host grass. The plant never took off and it faded away. Like I said. Tricky plants to grow. Back years ago,when I tried growing it: I wasn't as concerned about simulating the native environmental coditions the plants grew in; but I suspect that, even in ideal conditions,they would still be a challenge. There has been a lot of switching around with the family status of some of these genera. Wow, like snapdragons are now in the broomrape family ? Well Linaria vulgaris is at the moment in the plantain family,Plantaginaceae. All three connected in Lamiales.

OK. I’ve looked again more closely at no. 5. I thought the leaves were fleshy and shiny but now I don't think they are. Look at Horseweed, Erigeron canadensis.
