lava rock
Cooled magma remnant
Lava rock is volcanic rock formed when molten lava cools and solidifies.
It's typically porous, lightweight, and dark-colored—often black or reddish-brown.
Lava rock appears in landscaping, gas grills, and aquariums: We spread lava rock around the desert plants.
The porous texture helps retain moisture and provides drainage.
