Utricularia is one of the least commonly grown of all the Insectivorous plants - mainly because they are mostly rather tiny plants, and also probably because so many of them are aquatic or semi-aquatic. In addition, they have the least impressive traps, or meal catching mechanisms. This genus utilizes tiny inflated "bladders" to capture its near-microscopic prey. Since theyse bladders are at or below the soil line (or water line), they leave little for the observer to see. The topside foliage is also often very diminutive in many of the commonly grown species; at best forming carpets of little leaves - for which this species is no exception.
That all being said, Utricularia sandersonii is still one of the most loved of the genus. This South African species is rather unique in its flower form - most people immediately likening the flower to a rabbit: ears, tail, and all! Utricularia sandersonii "Select Biue" is, as the name implies, is a selection known for being a bit more highly colored than the norm. To top it off, it is not only a great grower but also a heavy and reliable bloomer.
As for culture: I reccomend use a mix of 2 parts peat and 1 part coarse sand. Use distilled, rain, or reverse osmosis water. Do not fertilize. In order to keep them constantly moist, I keep them in shallow trays filled with enough water so that the soil surface is an inch or so above the water line. They do best on the warm side - though they will tolerate cool night temps but just expect them to grow slower during that time of year. Bright light but not sun suits this one best, or use artifical lights.
