The Raven ZZ has been gaining popularity due to its unique qualities—it's not only one of the best low-maintenance plants but also rare with its striking blackish-purple leaves. These plants initially sprout lime green leaves, which gradually mature into a rich, dark color, effectively offering a two-in-one visual experience. 
Their glossy appearance adds an elegant touch to any space, and they thrive in medium to bright, indirect light while preferring dry soil between waterings. These versatile plants can grow up to 3 feet tall, making them an excellent choice for both beginners and experienced plant enthusiasts.
