Hi again Pamela. You have a hydrangea there that might root, but you do need to take off the flower head, so the stem will put its energy into making roots. That is the greenish white, large flower head.
The pink fluffy ones are Stocks, I think. They're a remote possibility for rooting, I'd say. Again you must remove all flowers and buds and don't be disappointed. They are easy to start from seeds in the spring.
The pink lily-like flowers are Alstromeria. They grow from tubers so most likely will not make roots for you.
Not sure what the greens are, very pretty, and if you were to strip off the lower leaves on those and put them into some potting soil there's a chance for rooting there.
The small peachy flowers are already dead, I think. Is the stem green or dark brown? In any case since there don't seem to be leaves I'd pitch that.
Wanted to say something important to you about your whole new venture into gardening. After reading so many of your posts about rooting things etc. the one thing you will absolutely learn as you become a gardener is patience. Some of these things will make roots fairly quickly, and some will take a month or maybe two - or not root at all before rot sets in. You need to be patient, give them time, and don't give up if it's not happening yet. It will. If not now, then in spring. You can't hurry plants.
