What kind of weed is this? (if it is)
These 2 kinds of what I think are weeds are growing in my container garden.
One of them has oval leaves with small flowers like things all along the stem. The leaves close in on the stem in the evenings. This one is not invasive. It is growing in only one of my containers.
The second one has white flowers and spreads like crazy. It started off in one container and has spread to many of them.
