The 12 Most Amazing And Uniquely Beautiful Houseplants You Never Knew Existed

Lithops plants (living stones): Lithops are fascinating little succulents. Sometimes called split rocks or pebble plants, living stone plants are extremely drought-resistant and are widely popular in low-water gardens in desert regions. They can be grown both indoors and outdoors, but outdoor growers should be careful that they don't get too much water. It's estimated that there are at least 37 species of lithops, and around 145 varieties. More varieties are regularly discovered or bred by hybridization.
