Please ID - weed or keeper?
The first plants got started in my yard after planting perennials that had been neglected at a greenhouse that burnt down. The perennials had sat in their pots outside for around 2 years so anything could have started in them. There are a few photos of this years plants and some of photos I took last year when there were larger.
The second plant is trailing and has spikes with purple flowers. Only a few of the flowers remain.
Are these keepers?
