Bucephalandra

Bucephalandra sp.

plantfreshwater

A genus of slow-growing rheophytic plants native to Borneo, prized in aquascaping for their thick, waxy leaves that come in a remarkable range of colors — from green and brown to blue, purple, and red — often with iridescent shimmer. They can be grown attached to rocks or driftwood like Anubias, tolerate low to medium light without CO2 injection (though CO2 accelerates growth), and are well-suited to shrimp tanks.
