This plant is fairly rare. One if the common names is Tree Lily. Its flower form is somewhat similar to Brugmansia and it shares the trait of night time fragrance. It is also known as Portlandia domingensis. It is not in the Brugmansia family but is in the Gardenia family. Under the right conditions it will grow to about 5 feet in a pot (more in the ground), though it can start blooming at ~ 2 feet. It can happily live in pots and as an indoor plant where it can handle lower light. Blooms off and on from Spring - Fall.
Interesting - Logees has a sale on it now for $19.95 for a 4" pot.

I have not personally grown this plant/tree but am temped by the Logee's offer.
