Chris, I can't tell from the pics for sure if the crested Purple Passion is crowning. If you are sure it is, you can cut off each end of the crested plant where you think the flowers will be coming from. The central portion should continue to grow in a crested manner. The two pieces you cut off can also be rooted. Because the plant is crested, there is a chance that the two flower-pieces will continue to grow in a crested form, and may not die. But definitely divide them so that they do not cause the main plant body to die off if it turns out to be flowering. Treat the cuttings like you would a rosette division (dry a day or two then plant). They should not be difficult to root (again, if not a pure flower stalk).
What you have is precious. Please try to preserve it.
