I got my Truly Tiny 2 years ago as a TC from Wellspring.
It took a long time to start growing from a TC compared to other TC's I've grown but now it's fully established and rolling.
I've already separated 3 pups and there's still 3 growing in the pot.
The one on the right is Super Dwarf Cavendish which I originally got as a pup so it's a lot bigger.
Besides the size both my Truly Tiny & SDC look identical.. Petioles, leaves, stem, etc.
I've seen other threads on here saying that they are both the same plant and even if there is a real Truly Tiny many are just rebranded SDC... so who knows.
I'm expecting my SDC to fruit sooner
