This special lava plant dares to grow on lava. Dare devil! A real lava plant! The Schefflera originates from Australia and owes its nickname ‘umbrella tree' to its typical leaves. As it grows upwards, new umbrella shaped leaves constantly form on this Schefflera on lava rock. This houseplant on lava rock draws its water from the porous lava rock and the watertight container. The lava plant gets its nutrition from the lava rock in the beginning. Who do you think deserves this rock?
