The raven ZZ plant (Zamioculcas zamiifolia ‘Raven’) is beloved for its striking dark purple almost black foliage So if you’ve noticed vibrant green new growth emerging on your raven ZZ it can seem confusing and concerning However, there’s no need to worry – green new shoots are totally normal for this variety.
Here’s an explanation of why raven ZZ produces lime green new growth along with tips for keeping your plant’s mature leaves dark and lush.
It’s Natural For New Growth to be Green
Raven ZZ plants naturally produce bright green new shoots that eventually turn dark purple So green new growth is not a cause for concern – it’s simply a stage in the plant’s development,
The stems begin green when they first emerge. Then over time, they darken to the deep blackish-purple that gives raven ZZ its dramatic, gothic look. Full color transformation can take several weeks to a few months.
As long as the older, more established leaves stay dark, you can enjoy seeing the new lime green shoots grow! With the right care, they’ll slowly turn the signature raven ZZ black color.
Why Does New Growth Stay Green?
While green new growth is normal, sometimes the shoots fail to darken and remain stubbornly green and vibrant.
There are a few key reasons this can happen:
-
Insufficient Light – Raven ZZ needs bright, indirect light to reach its darkest potential. Without enough light exposure, new growth stays green instead of maturing to black.
-
Underwatering: Letting plants dry out too much between waterings can make it harder for them to take in nutrients, which can cause light green new shoots.
-
Overwatering – Excess moisture damages roots, reducing their ability to take in nutrients needed for rich leaf color.
-
Low Humidity – Drier air prevents leaves from developing their deepest pigment. Misting and pebble trays can help boost humidity.
-
Lack of Nutrients: New growth that is chlorotic and light green is caused by a lack of key nutrients like nitrogen. Fertilizing corrects this.
-
Transplant Shock – Repotting and other disturbances can shock plants, causing paler growth. Allow time to recover.
-
Pests & Diseases – Pest damage and diseases disrupt nutrient flow, often yellowing new shoots. Inspect and treat plants.
So if your raven ZZ’s new leaves stay green, it’s usually signaling an underlying care issue. With a few adjustments, you can get that dramatic color contrast back.
Caring for Your Raven ZZ Plant
While green new shoots are typical for raven ZZ plants, you can follow best care practices to keep growth as vibrantly black as possible:
-
Light – Provide bright, indirect light to encourage deep black foliage. At least 4 hours of sun is ideal.
-
Water – Allow soil to dry out between waterings and reduce water in winter. Preventing overwatering avoids nutrient issues.
-
Soil – Use a well-draining potting mix amended with perlite, sand, or pumice.
-
Fertilizer – Apply a balanced houseplant fertilizer every 2-4 weeks in spring and summer when actively growing.
-
Temperature – Keep between 65°F-85°F. Avoid cold drafts which can shock plants.
-
Pruning – Remove any dead or damaged leaves and stems to encourage new growth.
With the right care and growing conditions, you can enjoy beautiful ink-black mature leaves that stand out against the lime green new shoots.
Patience is Key
It’s important to be patient and allow proper time for the raven ZZ’s green shoots to darken. Here are some tips:
-
Expect full transformation to take at least 4-8 weeks, sometimes longer for larger leaves.
-
Don’t move the plant around. Consistent conditions help leaves mature.
-
Avoid direct sun, which can scorch tender new growth before it pigments.
-
Older leaves darken first. Bottom leaves will remain green longer as lower ones mature.
-
If plants are stressed, color change can take longer. Eliminate any issues and be patient.
With time and maturity, the vivid green shoots will develop into the dramatic near-black leaves that make the raven ZZ plant so special.
When to Worry About Green Growth
While green new growth is typical for raven ZZ plants, vibrant lime green shoots can sometimes signal problems. Here are signs that indicate an underlying issue:
- Older leaves are losing color or fading to green
- No leaves are maturing to dark purple/black
- All new and old growth remains light green
- Green shoots over 6 months old with no color change
- Yellowing, wilting, or dying green shoots
If you notice these warning signs, your plant likely needs an adjustment to its care. Troubleshoot by checking for pests, increasing light, adjusting watering, changing location, inspecting roots, or repotting if necessary. With a few tweaks your raven ZZ will be back to producing stunning two-toned foliage.
Enjoy the Color Contrast
The striking green and purple color contrast is part of what makes growing the raven ZZ plant so fun. Now that you know it’s natural for new shoots to start off green, you can relax and allow them to transform at their own pace. With the right care, your plant’s maturing leaves will soon flaunt that gothic raven black you love.
