Good to see, I'm having another go with this species, my plant seems to of survived the winter and I transplanted it from peat based to sphagnum yesterday, no top growth yet

Great thread on a wonderful plant.
Cole Bonfield, a fellow Canadian CP enthusiast, noted that the leaves of his Utricularia reniformis were superhydrophobic in nature.
Water is repelled from their leaves, even bouncing up off the surface again after impact, before rolling away off the leaf.
The following video demonstrates some of these superhydrophobic properties.
It is also called the Lotus Effect, because Lotus leaves as it turns out are superhydrophobic by nature too.
This video goes into a bit more depth.
Cole also noted this trait with his U. reniformis x nelumbifolia plant's leaves.
Spray down a leaf and confirm if your plants are doing the same thing - can you see the water droplets actually bounce?
Had a look online for information pertaining to superhydrophobia and Utric leaves, but came up empty.

Confirmation of the hydrophobic nature of most of the leaves however notice that one leaf has a much less resistance. That leaf has not been treated any differently nor been in contact with anything that should have caused this anomaly.

Thanks for taking the time to do the test and then posting your results, Steve.  Noticed that the one anomaly leaf seemed to be a bit taller than the others, so perhaps an older leaf? Cole mentioned that his U. reniformis was the 'Mata Atlantica' strain. Apparently, superhydrophobicity (apologies for using the ten dollar word there  ) also occurs in more common plants like broccoli, brussels sprouts, cabbage, and turnip greens... ...repelling both water and children, alike.  dvg

These plants weren't that good at all last year. I was at one point becoming a little concerned. However, they've bounced back this year and there's a fine crop of aquaphobic foliage. I think I'll still be repotting at the end of the season.  |

Fred, you can also add kale to the list of gassy brassicas, with superhydrophobic leaves.
Do you have a pic for us, of your fine crop of aquaphobic foliage?
Cole thinks the water repelling quality, is a way for this species to support rather large leaves on long slender stems.
Large leaves and skinny stems isn't necessarily a problem if the leaves can readily shed water.
Fred did you make any other observations with regards to your plants leaves?
Just curious how well "bonded" this quality is in the leaves...
...does the aquaphobic nature of a leaf rub off easily, say with gentle pressure applied between a thumb and forefinger?

Was talking to Cole Bonfield yesterday and asked him a bit more about the leaves on his U. reniformis 'Mata Atlantica' plant. Asked him if the hydrophobic quality of this plant's leaves was due to a powdery or waxy coating on the leaf, which in turn could be rubbed off by mechanical intervention. Cole's response was that there was no waxy or powdery coating on the reniformis leaves that would rub off. If that is the case, then this feature seems to built right into the leaf, making a stronger argument for the superhydrophobic nature of these leaves. dvg |

Those are shaping up for a stunning show.
Do you know if the flowers can produce viable seed, if they are manually self-pollinated with a toothpick?
