Received a plant package yesterday, just wondering what some of these plants are 
plant 1
plant 2:
the one in front with thin leaves. It has a horizontal stem... it connects all the plants together. and it has a LOT of roots
it was pretty weird to plant (wasn't sure how to, lol)
another picture of plant 2
and also, should I cut the horizontal stems so that each "plant" stands by itself? or would that hurt it? thanks!
