[Bonanza]

You are either speaking about some new growth or the beginning growth of the flower. Don't cut off either one since you don't know what it is. The flower (somewhat insignificant as flowers go)as it fades will become seeds and will eventually dry up. If your ti is too 'leggy' you can cut it down to the height you want. It will then spurt new growth just below the cut. The bonus is you can stick what you cut off in the dirt and you will have a new plant. Make sure you don't let it get dry.
