Cultivation
U. inflata is one of the many Utricularia species that is cultivated by carnivorous plant enthusiasts. Because it requires no dormancy and due to its swift growth, it is one of the easier suspended aquatic species to cultivate. Barry Rice, author of Growing Carnivorous Plants, says that this species is the easiest suspended aquatic Utricularia that he has grown. Rice also mentions that U. inflata has been used as an aid in the cultivation of particularly difficult species, such as Aldrovanda vesiculosa, that are much more sensitive to high nutrient concentrations. When growing these species together, U. inflata will grow rapidly in the presence of higher nutrients, which allows A. vesiculosa to enjoy the conditions it thrives in.
Rice, the Washington Department of Ecology, and the United States Geological Survey's Nonindigenous Aquatic Species information resource all indicate that cultivation of this species is suspected as the most likely source of its introduction into Horseshoe Lake in Washington. The spread from lake to lake in Washington is probably the result of waterfowl moving from lake to lake and carrying plants or propagules with them.

Famous quotes containing the word cultivation:
“The cultivation of literary pursuits forms the basis of all sciences, and in their perfection consist the reputation and prosperity of kingdoms.”
—Marquês De Pombal (1699–1782)
“Those who are esteemed umpires of taste, are often persons who have acquired some knowledge of admired pictures or sculptures, and have an inclination for whatever is elegant; but if you inquire whether they are beautiful souls, and whether their own acts are like fair pictures, you learn that they are selfish and sensual. Their cultivation is local, as if you should rub a log of dry wood in one spot to produce fire, all the rest remaining cold.”
—Ralph Waldo Emerson (1803–1882)
“The cultivation of one set of faculties tends to the disuse of others. The loss of one faculty sharpens others; the blind are sensitive in touch. Has not the extreme cultivation of the commercial faculty permitted others as essential to national life, to be blighted by disease?”
—J. Ellen Foster (1840–1910)
