The Zanzibar Gem, scientifically known as Zamioculcas zamiifolia and affectionately nicknamed the "ZZ Plant," is a true superstar in the world of houseplants. Native to the dry grasslands and rocky terrains of Eastern Africa, this hardy beauty hails from countries like Kenya, Tanzania, and, of course, Zanzibar. It's celebrated for its glossy, emerald-green leaves and its near-indestructible nature, making it a favourite for beginner and experienced plant parents alike.

The ZZ Plant is renowned for its ability to thrive on neglect—perfect for those who might forget to water occasionally. It grows from rhizomes (thick, potato-like roots), allowing it to store water for weeks. Its architectural appearance and low-maintenance care needs make it a staple in homes and offices worldwide.

Whether you're a seasoned gardener or a houseplant newbie, here’s everything you need to know about keeping your Zanzibar Gem happy and healthy.

General Care for the Zanzibar Gem

Light

The ZZ Plant is highly adaptable, thriving in a wide range of light conditions. It prefers bright, indirect light but is also one of the few plants that can tolerate low-light spaces. If your home has dim corners, this plant will still survive and look fabulous. However, avoid placing it in direct sunlight for long periods, as this can scorch its glossy leaves.

Water

When it comes to watering, less is more. The ZZ Plant thrives on infrequent watering, thanks to its water-storing rhizomes. Water thoroughly once the top 2-3 inches of soil feel dry, typically every 2-3 weeks depending on the humidity and light levels. Overwatering is the number one enemy of the Zanzibar Gem, as it can lead to root rot.

Humidity

The ZZ Plant is not fussy about humidity and will thrive in average indoor conditions. It doesn’t require misting, making it a low-maintenance choice for any climate. If your home is extremely dry during winter, placing it near a humidifier can keep it looking lush, but it’s not essential.

Soil

A well-draining potting mix is essential for the Zanzibar Gem. Opt for a mix designed for succulents or cacti, as these soils allow excess water to escape quickly. Make sure the pot has a drainage hole to prevent water from pooling at the roots.

Indoors or Outdoors?

The ZZ Plant is best suited for indoors, but it can live outdoors in warm, frost-free climates. It thrives in shaded patios or verandas but should never be exposed to direct sunlight or freezing temperatures.

Yellowing Leaves:

Brown Tips:
