How to plant and repot the raven ZZ plant
Zamioculcas zamiifolia ‘Raven’ usually grows rather slowly. It isn’t necessary to repot yearly.
- Repot your raven zamioculcas every 2 or 3 years.
- Take advantage of repotting to split the plant if you’re so inclined.
Growing Zamioculcas zamiifolia Raven indoors
This plant will stay constrained to smaller sizes if you provide it with smaller pots.
- For it to grow to a full three feet (1 meter), give it a pot that is at least a foot and a half across (45 cm) and deep.
Growing Zamioculcas zamiifolia raven outside
- Find a shady spot in soil that drains very well.
Note that Zamioculcas zamiifolia raven cannot survive temperatures lower than 40°F or 5°C.
Watering Zamioculcas Raven
Zamioculcas raven, originating from the African-born Zamioculcas zamiifolia plant, is a flexible plant that can cope well with irregular watering.
- Watering in summer – Zamioculcas raven thrives when watered a small amount every two weeks.
- Watering in winter – this dormant phase means the raven ZZ plant only needs water once a month.
Allow the soil to dry out entirely before watering again. Zamioculcas raven has a tuber-like rhizome that stores water. Letting the soil dry out occasionally helps fend off root rot.
Proper exposure for Zamioculcas zamiifolia ‘Raven’
Zamioculcas raven will survive in very low light conditions, which makes it suitable for use in the office or even in poorly lit rooms like bathrooms. However, for it to thrive and grow, it helps to put it in a very well-lit place while avoiding direct sunlight.
- Place it near a window that faces the most sun (South in the Northern hemisphere, North-facing when in the Southern hemisphere).
- Ensure sun doesn’t land on it directly during the brightest hours (11 am to around 3 pm). Either set up a thin curtain veil or place it to the side of the window.
If you’re keeping the plant outdoors, prefer part sun only in the early morning or late afternoon.

Color and hue of the Raven ZZ plant
Time is what makes the black ZZ plant turn dark. Fresh leaves start out bright green and gradually turn black with time.
It may take up to two months for a stem and leaves to turn back completely, although usually it already gets dark after six weeks.
Hues drop from bright green to dark green to purple black, and exposure to strong lights or artificial lighting only marginally influences the coloration.
How to care for Zamioculcas raven
If ideal growing conditions are met, this plant can send up a new shoot rather fast, reaching growth of up to 1 cm/day or an inch in three days.
- New shoots are a surprising bright green! They will darken to a violet purple black as time passes.
However, most of the time it seems to stay dormant, either because conditions aren’t optimal or because temperatures have dropped and slowed growth, as in the winter season.
Diseases and pests that infect Zamioculcas zamiifolia raven
Zamioculcas raven is virtually invulnerable to insects and pests, at most hosting a few scale insects or mealy bugs that will move to other plants as soon a better choice arrives.
As regards diseases, the most probable infection you’ll encounter is a form of root rot that results directly from overwatering. Zamioculcas raven leaves will yellow and turn to mush.
- Check that the plant pot drains well
- Stop watering for 6 weeks all together
- Only resume watering after ensuring proper drainage for the pot and soil mix (clay pebbles, gravel, sandy soil…)
- Follow guidance above on how to water the raven ZZ plant properly
Propagating and multiplying the Zamioculcas Raven ZZ plant
This incredible plant is simply a special variety of Zamioculcas zamiifolia. Propagate and multiply it just as you would propagate Zamioculcas varieties that are more commonly found.
However, note that this plant variety has a plant patent on it and cannot legally be multiplied and sold in the United States. This is reserved to nurseries who have special agreements with the original breeder.
At most, simply propagate the plant to provide for a personal back-up in case your main plant dies off!

This recent creation is made available to us through the efforts of a Dutch houseplant grower, Van Winden-Erica B.V.
A distribution agreement was signed with Costa Farms for the United States. Costa Farms operates out of Florida and is rolling out availability of the raven ZZ plant in the Americas in 2018-2019.
Since the ZZ plant is also often called “Emerald palm“, perhaps this variety will pick up a similarly inspired name: the “Black Emerald” palm!
Toxicity of the Zamioculcas raven ZZ plant
Non-lethal calcium oxalate crystals occur in all parts of the plant and can be mildly irritating to sensitive skins. Wear gloves if you’re in that situation and you need to repot or split your Zamioculcas raven.
Cats, dogs and the Raven ZZ plant
The same calcium oxalate crystals can wreck havoc in your pet’s digestive systems if they ingest too much of it. Try providing alternative plants like nepeta, the cat plant, to satisfy their need of greens!
