Sorry about the bad quality photos -
my hummer's giant (just came in!) - on the right:
the pot on the left of that last shot - here's a closeup of my "regular" ceph. It has that one big growth point at the top of the pic from one root system, and another four off of another root. Those four tips came from a sliver of root that was the only thing left of a rotting plant that I rinsed clean (I lost the third root system RIP), cinnamon'd, and planted with its top right at the soil line about 4 1/2 months ago.
And yes, they're window sill plants
