Zamioculcas zamiifolia ‘Raven’, more commonly known as the ZZ Raven plant, is a striking cultivar of the classic ZZ plant. It’s renowned for its unique, dark, almost black foliage, which sets it apart from the more common green varieties. The “Raven” in its name is a nod to the deep, lustrous, purplish-black color of its mature leaves, reminiscent of a raven’s feathers.
The Allure of Darkness: What Makes the ZZ Raven So Special?
The ZZ Raven isn’t just another houseplant; it’s a statement piece. Its dramatic coloring provides a sophisticated contrast in any indoor setting, making it a favorite among minimalist designers and plant enthusiasts alike. But its appeal goes beyond aesthetics. Like its green counterpart, the ZZ Raven is incredibly resilient, making it an ideal choice for both seasoned plant parents and beginners who might not have the greenest thumb.
Its journey to that coveted dark hue is fascinating. New growth on a ZZ Raven typically emerges in a vibrant, almost neon green. Over several weeks, sometimes even months, these new leaves gradually darken, transitioning through shades of emerald and deep forest green before settling into their signature inky black. This transformation adds an element of anticipation and wonder to owning a ZZ Raven.
Unpacking the ZZ Plant Family Tree
To truly appreciate the ZZ Raven, it helps to understand its origins. The ZZ plant, or Zamioculcas zamiifolia, is a tropical perennial plant native to Eastern Africa, particularly drought-prone regions. It belongs to the Araceae family, which also includes popular houseplants like philodendrons and monsteras.
The standard Zamioculcas zamiifolia is characterized by its glossy, dark green leaves and thick, succulent stems. It’s celebrated for its ability to thrive on neglect, tolerating low light conditions and infrequent watering – traits that have earned it the nickname “eternity plant.”
Over the years, various cultivars have emerged, each with its own unique twist. Besides the ‘Raven’, you might encounter:
ZZ ‘Zenzi’
A dwarf variety with a more compact growth habit and tightly spaced leaflets. It’s perfect for smaller spaces or as a desk plant. Its leaves tend to be a darker green, almost a miniature version of the classic ZZ.
ZZ ‘Super Nova’
This cultivar boasts even darker, almost black foliage from a younger age than the ‘Raven’, and often has a more upright growth habit. It’s a striking plant that truly lives up to its name, radiating a kind of dark energy.
ZZ ‘Lucky Classic’
A popular variegated form, though true variegation in ZZ plants is rare and often unstable. When stable, it features splashes of cream or yellow on the green leaves, adding a unique dimension. However, many “variegated” ZZ plants are simply suffering from nutrient deficiencies or light issues, so it’s important to verify the authenticity of a ‘Lucky Classic’.
ZZ ‘Albino’ (or ‘Chameleon’)
This is an extremely rare and often unstable form with pure white or very light yellow new growth that may or may not green up over time. It’s highly sought after by collectors but can be challenging to maintain due to its lack of chlorophyll.
The ZZ Raven stands out among these for its consistent and dramatic color transformation, making it a reliable choice for those seeking that truly dark aesthetic.
Cultivating the Darkness: Caring for Your ZZ Raven
One of the greatest appeals of the ZZ Raven is its remarkably low-maintenance nature. It’s truly a plant that thrives on neglect, making it perfect for busy individuals or those who are new to plant care. However, “low maintenance” doesn’t mean “no maintenance.” Providing the right conditions will ensure your ZZ Raven flourishes and displays its deepest, most impressive coloration.
Lighting Up (or Not): The Right Light for Your Raven
While ZZ plants are famously tolerant of low light, the ZZ Raven benefits from bright, indirect light. This doesn’t mean direct sun; harsh, direct sunlight can scorch its leaves, especially the new, lighter green growth. Think of a spot near a north-facing window, or a few feet away from an east or west-facing window where it receives diffused light.
In lower light conditions, your ZZ Raven will still survive, but its growth may be slower, and the new leaves might take longer to darken, or they might not achieve that intense, inky black hue. If you notice your plant becoming leggy or stretching towards a light source, it’s a sign it needs a brighter spot.
Conversely, if you see yellowing or crispy edges on the leaves, it might be getting too much direct sun. Adjust its position accordingly. The beauty of the ZZ Raven is its adaptability, allowing you to find that sweet spot in your home.
The Thirst Quencher: Watering Your ZZ Raven
This is perhaps the most crucial aspect of ZZ Raven care, and where most new plant parents go wrong. ZZ plants, including the Raven, store water in their thick rhizomes (underground stems) and succulent leaves, making them highly drought-tolerant. Overwatering is the quickest way to send your ZZ Raven to an early grave.
The golden rule for watering a ZZ Raven is to allow the soil to dry out completely between waterings. And when we say “completely,” we mean all the way through the pot. You can test this by sticking your finger several inches into the soil, or by using a moisture meter. If it feels even slightly damp, wait.
The frequency of watering will depend on various factors: the size of your pot, the type of soil, the humidity in your home, and the amount of light your plant receives. In general, you might water every 2-4 weeks in the growing season (spring and summer) and even less frequently in the dormant winter months, perhaps once every 4-6 weeks. Some ZZ Raven owners even go months without watering their plants in winter.
When you do water, water thoroughly until you see water draining from the bottom of the pot. Ensure the pot has drainage holes – this is non-negotiable for ZZ plants. Never let your ZZ Raven sit in standing water, as this will lead to root rot. If you use a decorative cachepot, make sure to empty any excess water that collects at the bottom.
Soil and Potting: The Foundation for Success
A well-draining soil mix is paramount for the ZZ Raven. A standard succulent or cactus mix works wonderfully, or you can create your own by amending regular potting soil with perlite, coarse sand, or pumice to improve drainage. The goal is a mix that allows water to pass through freely, preventing it from becoming waterlogged.
When it comes to pots, terracotta pots are often recommended for ZZ plants because their porous nature helps to wick away excess moisture, further reducing the risk of overwatering. However, any pot with good drainage holes will suffice. Choose a pot that is only slightly larger than the plant’s root ball. ZZ plants actually prefer to be a little root-bound, and putting them in too large a pot can lead to excess soil retaining too much moisture, again, risking root rot. Repot only when the plant is clearly outgrowing its current pot, usually every 2-3 years.
Feeding the Beast: Fertilizing Your ZZ Raven
ZZ Ravens are not heavy feeders. They can thrive for long periods without any additional nutrients. If you choose to fertilize, do so sparingly and only during the growing season (spring and summer). A balanced liquid fertilizer, diluted to half or even quarter strength, applied once every 2-3 months, is more than enough. Over-fertilizing can lead to nutrient burn and damage your plant. During the fall and winter, when the plant’s growth slows down, cease fertilization entirely.
Humidity and Temperature: Comfort Zones
As a tropical plant, the ZZ Raven appreciates average to slightly above-average indoor humidity. However, it’s remarkably tolerant of drier air, making it well-suited for most home environments. You don’t typically need to mist your ZZ Raven or place it on a pebble tray, though it won’t hurt if you do.
When it comes to temperature, ZZ Ravens prefer consistent room temperatures between 65°F and 80°F (18°C and 27°C). They are not fond of cold drafts or sudden temperature fluctuations, so keep them away from open windows during winter months or air conditioning vents. They will suffer if exposed to temperatures below 50°F (10°C).
Keeping it Clean: Pruning and Maintenance
The ZZ Raven generally requires very little pruning. You might want to remove any yellowing or damaged leaves, which can be snipped off at the base of the stem. If a stem becomes too leggy or is growing in an undesirable direction, you can prune it back to maintain the plant’s shape. Use clean, sharp shears to make precise cuts.
Occasionally, you might notice dust accumulating on the glossy leaves. Wiping them gently with a damp cloth not only keeps your plant looking its best but also helps it to photosynthesize more efficiently.
Propagation: Creating More Darkness
Propagating a ZZ Raven is a rewarding, albeit slow, process. The most common and successful methods involve stem or leaf cuttings.
Stem Cuttings
Choose a healthy stem with at least two sets of leaves. Using a clean, sharp knife or shears, cut the stem just below a node. Allow the cut end to callus over for a few days to a week. This helps prevent rot. Once callused, you can place the cutting in water or directly into a well-draining potting mix.
If rooting in water, change the water every few days to keep it fresh. Roots can take several weeks to a few months to appear. Once a good network of roots has formed, you can transplant the cutting into soil.
If rooting directly in soil, ensure the soil is lightly moist, not soggy. You can cover the pot with a plastic bag to create a mini-greenhouse effect and increase humidity, which can speed up the rooting process. However, be sure to air it out periodically to prevent fungal issues. Again, patience is key here; it can take months for new growth to emerge.
Leaf Cuttings
This is an even slower but equally viable method. Gently pull a healthy leaf from the main stem, ensuring you get a bit of the petiole (the small stalk that attaches the leaf to the stem). Allow the leaf to callus for a day or two. Then, insert the petiole end into a well-draining soil mix. You can lay multiple leaves on the surface of the soil.
Keep the soil lightly moist. Eventually, tiny rhizomes will form at the base of the leaf, and then, after many months, a new plantlet will emerge. This process requires significant patience, as it can take up to a year or even longer for a substantial new plant to develop.
Regardless of the method, remember that ZZ Raven propagation is a marathon, not a sprint. The rewards, however, are well worth the wait.
Common Problems and Solutions for Your ZZ Raven
Even with their resilience, ZZ Ravens can encounter a few issues. Knowing what to look for can help you address problems quickly and keep your plant healthy.
Yellowing Leaves
This is often the most common symptom and usually points to overwatering. If you notice lower leaves turning yellow and feeling soft or mushy, reduce your watering frequency immediately. Allow the soil to dry out completely, and then extend the time between waterings. In severe cases, you might need to unpot the plant to check for root rot. If roots are brown and mushy, prune them away and repot in fresh, dry soil.
Yellowing can also be caused by underwatering, though this is less common with ZZ Ravens. In this case, the leaves might be crispy and dry. If this is the case, give your plant a thorough drink.
Nutrient deficiency can also cause yellowing, but given how little ZZ Ravens need to be fertilized, this is usually a secondary cause, if at all.
Drooping Stems
Drooping stems can indicate either overwatering or severe underwatering. If the stems feel soft and mushy, it’s likely overwatering. If they feel brittle and dry, it’s likely underwatering. Check the soil moisture to confirm the issue and adjust your watering schedule accordingly.
Brown or Crispy Leaf Edges
This is typically a sign of too much direct sunlight. Move your ZZ Raven to a spot with bright, indirect light. It can also be caused by very low humidity, though ZZ Ravens are generally tolerant of dry air.
Stunted Growth
If your ZZ Raven isn’t growing much, it could be due to insufficient light or a need for nutrients. While they tolerate low light, brighter indirect light promotes more robust growth. If it’s been a very long time since you fertilized (and it’s growing season), a diluted feed might help. However, remember they are slow growers by nature.
Pests
ZZ Ravens are relatively pest-resistant, but they can occasionally fall prey to common houseplant pests like spider mites, mealybugs, or scale. Inspect your plant regularly, especially the undersides of leaves. If you spot pests, isolate the plant and treat it with an insecticidal soap or neem oil solution. A cotton swab dipped in rubbing alcohol can also be effective for removing individual pests.

Frequently Asked Questions (FAQs)
How often should I water my ZZ Raven?
You should water your ZZ Raven only when the soil has completely dried out, all the way through the pot. This could be anywhere from every 2-4 weeks during the growing season (spring and summer) to once every 4-6 weeks or even longer in the dormant winter months. Always err on the side of underwatering rather than overwatering.
Will my ZZ Raven’s new leaves turn black immediately?
No, new growth on a ZZ Raven typically emerges in a bright, vibrant green. Over several weeks to a few months, these new leaves will gradually darken, transitioning through shades of green before reaching their characteristic inky black color. This transformation is a normal and fascinating part of the plant’s development.
Is the ZZ Raven plant toxic to pets or humans?
Yes, like all ZZ plants, the ZZ Raven contains calcium oxalate crystals, which can be irritating if ingested. It’s advisable to keep the plant out of reach of curious pets and young children. If ingested, it can cause irritation to the mouth, throat, and digestive system. It’s always a good idea to wear gloves when handling the plant, especially if you have sensitive skin, as the sap can cause mild irritation.
Why are my ZZ Raven’s leaves turning yellow?
Yellowing leaves are most commonly a sign of overwatering. If the leaves are soft and mushy, you’re likely watering too frequently. Allow the soil to dry out completely between waterings. Less commonly, yellowing can be due to severe underwatering (in which case the leaves would be crispy) or a lack of light.
Can I put my ZZ Raven in direct sunlight?
No, direct sunlight can scorch the leaves of your ZZ Raven, especially the new, lighter green growth. While it tolerates low light, it thrives in bright, indirect light. A spot a few feet away from an east or west-facing window, or near a north-facing window, would be ideal.
