Description: This lightweight, highly porous volcanic rock provides a dramatic, high-contrast groundcover with a deep, consistent charcoal-to-black color. Its jagged, highly textured surface prevents wind and water displacement, while the porous structure offers superior drainage and moisture retention for plant roots. It is a durable, low-maintenance, and permanent alternative to organic mulch, suppressing weeds and resisting fading.
Best Use: Modern landscape accents, decorative groundcover that makes greenery pop, improving drainage, in fire pits, and for areas where weight is a concern.
