Okay... number three looks like a beat up plantago major, to me.... put the stem apart, see if two or three threads cling on.... if plantago Major it is edible when young.

Is it a vine? It may be Solanum jasminoides, or potato vine. I lived for over 20 years in Northern CA and only one time did I see pokeweed, but don't know if poke grows in the Central Valley (I know the climate is definitely not the same there as in Sonoma!) But Potato Vine seemed to be pretty much a universally used fast, thick grower for problem areas. The individual blooms will look a bit like those of tomato plants, and its purple berries are small. Stems and foliage often take on a purple tinge depending on light exposure. Folks either love it because of its vigor and reliability or hate it because it's "overused."

It's been growing all summer on a southeast facing slope, basically sun all the heat of the day, with no water and expanding in size. Definitely a hardy thing! Big healthy canes compared to the 1/4" stems of the cut flowers that I rooted (only a few made it) in the spring. Would be a great grow on a slope and leave alone rambler. The scent was so powerful I smelled it on the breeze going 75 miles an hour and looked until I saw it up ahead and across the freeway! The bright pink flowers (what I call "hot pink") gave it away. It is growing at an almost 2,000 ft. elevation in uppermost Shasta County on Hwy 5. Hot in the summer and some snow in the winter.

How about Allium unifolium?
