I found photos of the plant online, and you were right!!! It is aggregatum!!! I also have 2 jenkinsii, so this has been a great amount of help!!! I am growing it in an east window, it seems happy!!! Thanks!
Glad I could help! It's always nice to take a plant out of NOID world. I don't know how long you've had it, but when you said it never bloomed, I was wondering if you were giving it a winter rest period. It absolutely needs it. Too bad the flowers don't last very long! I guess you'll be 100% sure of what it is once it blooms!
