If you are talking about a syringa; it is not screaming yellow, but soft yellow, and it can take up to 3 years before it blooms, if you prune it right ( which is not at all if you can avoid it) and the flowers can take several years to reveal their real colour. Mine have been blooming white for a few years!
I wouldn't stick them in a pot, but you could probably give it a try in a half barrel or something of that size.

You want to read about pruning them, they bloom on 2 year old wood! Snipping off too much will result in no blooms.
