I've also noticed that U. dichotoma will produce much larger bladders than
"normal" from the stolons growing out of the bottom of my pots (just in the
water tray - no soil). These larger bladders are at least a few millimetres
across.
Another terrestrial is U. praelonga which has largish bladders (2 or more mm
across). I find this plant quite undemanding to grow. As a bonus, it has
large, attractive yellow flowers.
