Selaginella lepidophylla is the resurrection plant also known as the ‘Rose of Jericho’. A resurrection plant that has balled up and appears dried out is simply dormant from lack of water. It is called a resurrection plant because once it has been watered, it will change color from brown to green. Do not be deceived by its initial appearance.
There are indeed people who are brown thumbed and prone to kill plants. One need not worry about this plant. In order to revive it, just water it. If you forget to water it, it shrivels and turns brown. Water it again even after weeks of neglect and it will enchant you with its resurrection ability.
