As the Black Raven grows, new, green growth turns black
An amazing cultivar of the ZZ plant. Very little water needed and perfect in very low light
ZZ Plant Care
Average warmth is fine of approximately 60-75°F (15-24°C) and no lower than 45°F (8°C).
Bright light is good but not essential. The zamioculcas zamiifolia grows fine with low levels of light, but it's best to avoid direct sunlight.
Allow the soil to become dry at the top to the touch between watering and do not over water. It's best to water this plant less than too much because over-watering can cause stem and rhizome rot.
Most well draining potting mixes will suffice that contains a high amount of perlite or sand within the mix (you can add more perlite or sand if needed to a mix that is bought). Good drainage holes at the bottom of the pot is essential.
I would re-pot the zz plant once a year at the beginning of spring, especially during the first 3 - 5 years - whilst it's growing up.
During the main growing season (April - August) feed with a balanced liquid fertilizer which is diluted, once a month.
Average house humidity is advised but increase humidity if the artificial heating within the home or workplace is quite dry.
You may propagate by dividing rhizomes or with leaf cuttings. Leaf cuttings have to be placed in a pot with a plastic covering and then the wait for roots to begin growing, which could take up to a year.
Cut away leaflets that are turning yellow near the base of a stem. Once a stem has grown much longer than all other stems you can remove that stem or cut it to size at the tip. The problem with cutting it to size at the tip is it can look quite odd, so removing it completely might be the best option.
