Like all the other Elders he has been in existence since the Big Bang and thus is nearly immortal, extremely powerful, and absolutely obsessed with what he takes his name after.

The Gardener was among the Elders that allied together to restart the universe by killing Galactus. Like any Elder of the Universe, he was made compltely immortal due to the mechinisms of the Grandmaster against the cosmic entity Death. Even should he loose his obsession he will not die.
