Zamioculcas zamiifolia 'Black Queen'

Description

A striking cultivar of the classic ZZ Plant, Zamioculcas zamiifolia ‘Black Queen’ is known for its almost jet-black leaves that slowly darken as they mature. The glossy, upright leaflets create a strong architectural form that feels equally at home in mid-century, minimalist, or art deco-inspired spaces. Like all ZZs, this plant stores water in its thick rhizomes, allowing it to tolerate long periods of drought and low light—making it a favorite among both beginners and collectors.

How to Grow Indoors

Provide bright gentle light for best coloration, though Black Queen will also tolerate lower light levels. Too little light may result in slower growth and greener leaves. Use a well-draining soil mix with added perlite or orchid bark to prevent root rot. Water deeply but infrequently—allow at least half the soil to dry before watering again. Overwatering is the most common cause of issues. Feed with a balanced liquid fertilizer every 6–8 weeks during the active growing season.

How to Grow Outdoors (San Francisco Bay Area)

In the Bay Area, Black Queen can live outdoors year-round in protected, frost-free locations. Place it on a shaded or filtered-light patio where it’s sheltered from direct afternoon sun and winter rain. Hetch Hetchy tap water is generally safe for ZZs. Bring indoors if temperatures drop below 50°F for extended periods.

Blooming

While not grown for its blooms, mature plants may produce small, pale spadix-type flowers near the base during warm months. These are subtle but add to the plant’s charm.

Pet Safety

Not pet safe — ZZ plants contain calcium oxalate crystals, which can cause irritation if ingested. Keep out of reach of pets and children.

Origin

Native species from Eastern Africa; cultivar origin uncertain.
