If you've been scrolling plant shops and can't decide between the near-black leaves of a raven zz plant and the glossy green of a classic zz plant, you're not alone. Both come from the same species, Zamioculcas zamiifolia, but they behave differently enough in your home that the choice matters. This guide breaks down light needs, growth speed, price, and the mistakes people make with each one, so you can pick the right zz plant for your space instead of guessing.
Quick answer
The raven zz plant is a cultivar of the standard green zz plant, bred for leaves that darken from lime green to near-black over 6 to 8 weeks. It needs slightly brighter indirect light to hold that color and grows a touch slower. The green zz plant is the more forgiving, lower-light, budget-friendly option, while the raven is the pick if you want a striking, near-black houseplant and can give it medium to bright indirect light.
What actually separates a raven zz plant from a green zz plant
Both plants share the same rhizomes, the same potato-like water storage roots, and the same waxy, feather-shaped leaflets. The raven zz plant is a sport of the standard green species: a single naturally occurring dark-colored branch that plant breeder Hyuk Jin Lee spotted on an otherwise ordinary zz plant at a South Korean nursery in 2006. He propagated cuttings from that branch, all of them grew black, and the trait held across generations. The US Patent and Trademark Office granted a plant patent for it on December 25, 2018, under the cultivar name 'Dowon,' marketed under the trademark "Raven" (NC State Extension plant profile; origin account via Nature & Garden).
Here's the part most plant shop tags skip: new raven zz leaves come out lime green, not black. Growers who sell the cultivar describe the same pattern: leaves emerge a bright, almost neon green, then shift through olive and deep burgundy before settling into near-black over roughly 6 to 8 weeks (Soltech grow guide). If you buy a raven zz and see fresh green growth at the base, you've got a healthy plant on its normal schedule, not a mislabeled green zz plant.
Pro tip: if a raven zz plant's mature leaves start turning back toward green instead of staying dark, that's a light problem, not a reversion to the "original" species. Move it closer to a window.
Light requirements compared
This is where the two plants genuinely diverge, and it's the single biggest factor in picking the right one for your room.
| Factor | Raven ZZ plant | Green ZZ plant |
|---|---|---|
| Minimum light to survive | Low indirect light, but color fades | Low indirect light, holds up well |
| Ideal light for best color/growth | Medium to bright indirect, 600 to 800 foot-candles | Medium indirect, 200 to 500 foot-candles |
| Direct sun tolerance | Tolerates brief morning sun, scorches in hot afternoon sun | Same, avoid harsh afternoon sun |
| Windowless office or bathroom | Not recommended, leaves green out | Survives under fluorescent light for months |
A green zz plant is the one you put in a dim hallway and mostly forget about. A raven zz plant in that same hallway will survive, but within a few months, its dramatic black color will fade back toward green as the plant produces more chlorophyll to compensate for low light.
Common mistake: buying a raven zz for a north-facing room with one small window and expecting showroom-dark leaves. You'll get a fine plant, just not a black one.
Growth rate and mature size
Both plants are slow growers by houseplant standards, and that's a feature, not a flaw, if you don't want to repot often.
A healthy green zz plant typically pushes 2 to 4 new stems during its active growing season from spring through early fall, reaching 2 to 3 feet tall indoors over several years. The raven zz plant grows at a similar or slightly slower rate, often 1 to 3 new stems per season, and tends to top out a bit shorter, around 18 to 24 inches, at least in its first 3 to 4 years.
Neither variety will fill an empty corner fast. If you want quick visual impact, a zz plant of either color isn't the right pick.
Care requirements side by side
| Care factor | Raven ZZ plant | Green ZZ plant |
|---|---|---|
| Watering frequency | Every 2 to 3 weeks, when top 2 to 3 inches of soil are dry | Same schedule |
| Soil mix | Well-draining, 60% potting soil to 40% perlite or cactus mix | Same mix works fine |
| Humidity | Tolerates 30 to 50% household humidity | Same, no misting needed |
| Fertilizer | Balanced liquid feed diluted to half strength, once monthly in spring and summer | Same schedule |
| Ideal temperature | 65 to 79°F (18 to 26°C) | Same range |
Day to day care is nearly identical between the two. The rhizomes on both varieties store water, which is why overwatering, not underwatering, kills most zz plants. If the lowest stems on either variety turn yellow and feel soft or mushy at the base, that's rhizome rot, usually from soil that never fully dries out between waterings.
Price and availability: why the raven costs more
A standard green zz plant in a 6-inch nursery pot usually runs $12 to $20 at most garden centers. A raven zz plant of the same pot size often costs $30 to $55, and smaller 4-inch starts can still run $18 to $25 because of how it's propagated.
The real driver is legal, not just biological. The raven zz plant holds US plant patent PP30035, protected through 2033, so only nurseries licensed by the patent holder can legally propagate and sell it; Costa Farms holds exclusive US propagation rights, and Van Winden-Erica B.V. holds the "Raven" trademark and distributes it across Europe (Nature & Garden). That licensing bottleneck limits supply far more than any difference in rooting speed. Given how patent-protected plants have historically priced out over their protection period, expect the gap to narrow as more licensed growers come online before 2033, similar to what happened with other formerly exclusive patented plants.
Which one should you actually grow
Pick based on the room, not just the look you like in photos.
- Choose the green zz plant if your space has a single small window, north-facing light, or mostly artificial lighting, or if you want a lower-cost, low-maintenance plant for an office desk.
- Choose the raven zz plant if you have a spot with medium to bright indirect light, such as a few feet back from an east or west-facing window, and you want a plant that reads as sculptural and dark against light-colored walls.
- If you're not sure how bright your space really is, a light meter app on your phone (aim for 600+ foot-candles near the plant) will tell you more than staring at the window and guessing.
Practical tips for growing either variety
- Check soil moisture with a wooden skewer, not a finger. Push it 3 inches down; if it comes out clean and dry, it's time to water.
- Rotate the pot a quarter turn every 2 to 3 weeks so growth doesn't lean toward the light source.
- Wipe leaves with a damp cloth once a month. Dust buildup blocks light and slows photosynthesis on both varieties.
- Repot only every 2 to 3 years, and size up just one pot diameter at a time. Zz plants prefer being slightly root-bound.
- If you're chasing darker raven color, give it bright indirect light for at least 6 hours a day rather than moving it around trying different spots.
Common mistakes with raven and green zz plants
- Watering on a fixed schedule instead of checking soil. Both varieties store water in their rhizomes, so a weekly watering habit left over from other houseplants will eventually cause rot.
- Assuming a raven zz plant is a different species that needs totally different care. It doesn't. The care overlaps by about 90%; only the light requirement shifts.
- Panicking over new green growth on a raven zz plant. New leaves always emerge green before darkening. This is normal, not a defect or a mislabeled plant.
- Using a pot with no drainage hole. This is the single most common cause of rhizome rot in both varieties, more than overwatering frequency itself.
- Placing a raven zz plant in a dark corner "because zz plants tolerate low light." That's true for the green species; the raven trades some of that low-light tolerance for its color.
Expert insight
Most care sheets treat "zz plant" as one plant with one light requirement. In practice, the cultivar you own changes that answer. If you've kept a green zz alive for years in a dim room and then buy a raven zz for the same spot expecting identical results, you're the most common source of "my raven zz turned green" complaints in plant forums. The fix is more light, full stop; extra water or fertilizer won't restore the color.
Frequently asked questions
Is a raven zz plant rare?
It's less common than the standard green zz plant and costs more, but it's widely available online and at specialty nurseries as of 2026. It's uncommon, not truly rare.
Will my raven zz plant turn back to green?
Leaves that are already fully dark won't reverse color, but new growth will be greener if the plant doesn't get enough light, and older leaves can look duller over time in low light.
Can I propagate a raven zz plant from a single leaf?
Yes. A single leaflet placed in water or moist soil can root and eventually grow a small rhizome, though this process often takes 4 to 6 months before you see a new shoot, and success rates are lower than with stem cuttings.
Are raven zz plants toxic to pets?
Yes, both raven and green zz plants contain calcium oxalate crystals in their sap, which can cause mouth irritation, drooling, and vomiting if chewed by cats or dogs. Keep either variety out of reach.
Do raven and green zz plants need different pots?
No. Both need a pot with a drainage hole and can go in the same terracotta or plastic containers. Terracotta helps excess moisture evaporate faster, which benefits both varieties equally.
Why is my zz plant, raven or green, dropping leaflets?
Individual leaflet drop from an otherwise healthy stem is often normal aging, especially on lower older leaves. Widespread yellowing and dropping across the whole plant usually points to overwatering.
Can I grow a raven and green zz plant in the same room?
Yes, as long as the room has a bright spot for the raven and you're fine with the green zz doing slightly better in the dimmer corners of that same room.
Final word
The green zz plant and the raven zz plant are the same tough, forgiving houseplant underneath, just tuned for different light conditions and different looks. Match the variety to the actual light in your room rather than the one that photographs better, and either one will reward you with years of low-maintenance growth. If you're still not sure which fits your space, take a photo of your intended spot at midday and compare it against the light table above before you buy.
