3 different patches of weeds appeared after all the rain we’ve had. Need help in identifying them. Thanks
weed number 1 is Diodia virginiana, buttonweed. Weed number two is Ludwigia palustris, Marsh purslane, weed three may be Callitriche terrestris but could also be Ludwigia microcarpa or a species of Hemianthus—the flowers and fruits are tiny so you should consult the internet on this one.
