You can cut the blooming branch and make a new standard. The blooms should open and you'll have a new plant. You need to place the cutting in a few inches of water and watch for the lenticels (nubbies) to appear around the bottom of the cutting stalk. When you see little white protrusions, you can pot it up. J.T. has some great articles on growing cuttings.
You really should bump up the pot size for your main brug.
