What is the vegetation like in planet Uranus?

The composition of Uranus's atmosphere is 82.5 percent molecular hydrogen, 15.2 percent Helium, and 2.3 percent Methane. Trace amounts of Hydrogen Deuteride exist, with possible aerosols of ammonia ice, water ice, ammonia hydrosulfide, and methane ice. The atmosphere of Uranus is made up of 83% Hydrogen, 15% Helium, 2% Methane, and small amounts of Acetylene and other Hydrocarbons. In the lower atmosphere there are water-ammonia crystals. There is no "air" on Uranus, which is the coldest true planet*. The atmosphere is a mix of hydrogen, helium, methane, and ammonia at a minimum temperature within 50 Celsius degrees of absolute zero. Deep in the atmosphere, the crushing pressure results in a "hot slush" of water and ammonia at 5000° C. This is "cold" compared to the other gas giants, as Uranus seems to have lost much of its internal heat. *Pluto and the other trans-Neptunian dwarf planets are still colder, as they have almost no internal or solar heating.
