    Mine grows in an undrained box with the water kept around 1" above the top of the surface of the media, occasionally dropping to the same level as the top of the media. Been in flower constantly since last summer.

    So, would I be able to grow one of these in a ten gallon terrarium? Or would it need more space? I'm not suggesting that I fill the tank with water, but rather that I have lots of plants growing in it under growlights, which I do. So, technically, it could be grown as a terrestrial, with lots of flooding, right? That's how I grow my U. dichotoma, with the water level almost always at or above the surface of the soil.

    My undrained plastic tub is small. Dimensions about 6" square by 4" deep, with about 3" of substrate. One to two pints' capacity?

    I wouldn't say as a terrestrial with lots of flooding, but rather as a flooded anchored semi-aquatic, with periodic water fluctuation down to the surface level being tolerable only. It wants its leaves under shallow water as much as possible. The leaf structure of U. biloba is the typical feathery design of most other aquatic utrics.

    U. dichtoma is different - it is a terrestrial that tolerates flooding. The morphology (such that it is) of the plant is that of a terrestrial utric.

    I would not recommend growing U. biloba as a terrestrial with occasional flooding or water at the top of the soil, but by all means try as it unlikely to harm the plant - although I would have less confidence in successful/prolific flowering in such conditions.

    Cheers.

    Utricularia biloba will grow happily as a terrestrial but does not produce the long pinnate leaves that it does when grown submerged. Instead it grow small leaves similar to those of U. subulata except thinner. A significant portion of its life in nature is spent as a regular terrestrial species would when the water recedes during the warmer months of the year. I've seen it growing in its natural habitat in Sydney.
