the geranium, centre, leaning over spider plant, looks like one that will become too large for its neighbours. I'd remove that and put it in the garden but it's OK for the rest of the summer. and just below and to the left, between geranium and persicaria. That's a willowherb, a weed, Get that out as well. The spider plant wouldn't survive a hard winter but lots of people put them out in summer.
