Yep, I have a little bulb about an inch across with a tiny shoot that is the same 'vintage' as yours, Mj. At least they made a bulb, though! I'm guessing that's why Tropiflora charge so much for their full-grown ones. Takes forever to grow them?
Tomorrow I will go and disturb the Mama plant just to see how big that tuber is and give her some fresh potting mix. This is her 4th season with me, I think, and I got her as a full size plant.
You're really going to cut off that pretty flower, Drew? Mine self-pollinated and seeded herself the first year she made a flower. But you're probably right, the leaves might get bigger and last longer if you don't let the flower mature. I'm going to try that with my Thai caladiums this year.
