About Calathea Zebrina Starter

Goeppertia zebrina 'Starter' · also called Starter zebra calathea · houseplant

The zebra plant, with broad velvety leaves striped in alternating bands of light and deep green, sold here as a young 'Starter' plant.

It folds its leaves upward at night, matures into a bold clump, and is non-toxic to cats and dogs.

Preferred mix: Light, moisture-retentive, free-draining mix

Watch for — Yellowing leaves: Overwatering or waterlogged soil; improve drainage and let the surface dry slightly between waterings.
