Sinningia 'Anne Crowley'

Tubers can survive a lot of hardship.  Most of the right half of this tuber of Sinningia 'Anne Crowley' rotted during a particularly cold winter, but the tuber managed to seal off the damage.  The crater on the right shows where the damaged area was.  In this view, we can see about a half dozen new shoots from the living center of the tuber.  However, if all the potential growth points of the tuber are killed, the tuber will never again sprout new growth.  Just as this tuber that I hold in my hand will never again bear leaves of green...

Sorry about that.  See, there was this guy named Tannhäuser...  Never mind, I guess you had to be there.
