The Zanzibar Gem, scientifically named Zamioculcas zamiifolia and often referred to as the "ZZ Plant," is a true gem for houseplant enthusiasts across Europe. Native to the dry grasslands of Eastern Africa, including regions in Kenya, Tanzania, and Zanzibar, this hardy plant is as resilient as it is stunning. Its glossy, deep green leaves and ability to thrive on minimal care have earned it a reputation as one of the easiest plants to grow indoors.
The ZZ Plant is not just about good looks—it's also a survivor. It stores water in its rhizomes (underground, tuber-like structures), allowing it to endure weeks without watering. Its sleek, sculptural form and durability make it an excellent choice for both modern interiors and traditional homes. Whether you're a seasoned green thumb or just starting your plant journey, this guide will help you keep your Zanzibar Gem thriving.
General Care for the Zanzibar Gem
Light
The ZZ Plant is a versatile houseplant that can handle a range of lighting conditions. It thrives in bright, indirect light but is also one of the few plants that can tolerate low-light areas—a lifesaver for European homes with fewer sunny days. Place it in a well-lit room but avoid direct sunlight, which can damage its leaves.
Water
When it comes to watering, the Zanzibar Gem prefers a "less is more" approach. Its rhizomes store water, making it drought-tolerant. Water only when the top 5-8 cm of soil feels dry, typically every 2-4 weeks, depending on the season and indoor humidity. Overwatering can quickly lead to root rot, so it’s better to err on the side of underwatering.
Humidity
The ZZ Plant thrives in average European indoor humidity levels and doesn’t require extra misting, even during dry winter months. However, if your home has particularly dry air due to central heating, placing the plant near a humidifier can help maintain its lush appearance.
Soil
A well-draining soil mix is key for keeping your ZZ Plant healthy. A blend designed for succulents or cacti is ideal, as it allows excess water to drain easily. Make sure your pot has a drainage hole to prevent waterlogging, which can harm the roots.
Indoors or Outdoors?
The Zanzibar Gem is primarily suited for indoor living in Europe, where winters can be harsh. However, in regions with mild, frost-free climates, it can also thrive outdoors in a shaded garden or balcony during the warmer months. Just ensure it’s protected from direct sunlight and temperatures below 10°C.
