These plants do not respond to the old adage "If it's a valuable plant and you pull on it, it will come up easily. If it resists, it's a weed." Numbers one and two, I suspect of being Portulacas. Number three looks like perhaps a Nicotania? Numbers four and five seem to be milkweeds of some sort (flowers and fruiting body) - they're where I find Monarch caterpillars, almost exclusively. Numbers six and seven, no clue, but boy, do I ever have a lot of them! They've been popping up and carpeting on the paths in my orchard. Number 6 is the flowers/fruit, and number 7 is the leaves of a newer shoot. Thanks for all your help!
1-2 is purslane and yes, it's in the portulaca family. it's edible (raw in salad). the others i've no idea. the white flowered one is pretty tho...i wouldn't call that one a weed!! :)
