Morning Glory

I never thought my pitiful stunted hail bitten morning glory would bloom but when I woke up this morning it has a beautiful flower smiling victoriously at me.

This is a photo of the front door of Michael and my townhouse.
I love my yellow tulips, they are so cheerful! Michael brought them home for me last week. I don’t know if I will be able to transplant them after the blooms die though. I have read mixed results of doing that as the bulbs were probably forced in a greenhouse before shipping to retailers.
Regarding the title of this post though, mornings glories. Am I asking for trouble if I plant a morning glory vine under that window? It will have a window box outside it shortly. I remember my parents having morning glories when I was growing up and they were so incredibly beautiful. However I remember them getting enormous and unruly.
So, if I plant one will it be impossible to control or will I be able to keep it on a trellis? My front door is west facing and I live in a zone 4 area by the way.
I’m not sure what else I am going to plant in that little bed yet though I like plants that I can eat (I am open to suggestions here.) I mights have a rather prolific amount of basil, parsley and chives shortly as I decided to grow them from seed. (If you are local you might be getting seedling gifts from me for awhile…)
I have a separate question too, still flower related though. What are these?:
I saw them in a raised bed in a parking lot today. They were a thick carpet of the most beautiful tiny purple flowers (the photo does not do them justice.)
I have a feeling most of my favorite flowers might be weeds…
EDIT: The purple flowers are called Creeping Phlox. Thank you for the id Aunt Ruth!
