Is the ZZ a “Clear Air” Houseplant?
Although, the ZeeZee did not find it’s way into the NASA Clean Air Study (it was not commercially grown at the time of the study) many of its cousins are considered “Clean Air Plants.” Its durability and toughness would make me place in the “clean air” category.
I grew Zamioculcas 40 years ago but wasn’t smart enough to introduce or grow it on a large scale :).
The base of the swollen stalks (rhizomes) host dark green foliage, naturally glossy leaves. Making it easy to assume someone applied leaf shine to the plant.

They make an excellent accent plant in areas where can grow and “spread its wings.”
As for being a tough, durable indoor plant, ZZ plant flower handles low indirect light well, the dry air of a home and abuse exceptionally well, it even grows.

How Do You Care For A ZZ?
ZZ Plant Soil Requirements and Plant Fertilizer Needs?
The ZZ plant does not need any special type of potting soil mix. Any well-drained mix recommended for houseplants will work.
As for the fertilizer requirements. A complete, balanced liquid fertilizer for houseplants (20-20-20) applied once per month when watering will provide the nutrients the ZZ needs to grow well.
ZZ Plant Handles Lower Lighting Levels Well
Even though the plant does fine in lower light levels, by placing it in bright indirect lighting it performs even better. It is one of the plants that thrive in fluorescent light.
Keep the plant away from any hot direct sunlight as the plant can burn. Good bright filtered afternoon sun would work well.
Don’t Let Emerald Gem Sit In Water
Don’t let the plant to sit in water or stay wet or you may experience root rot. The plant does better when kept on the dry side. If you water the ZZ too much or the plant sits in water you may find yellowing leaves.
A little more about watering from my side. I purposely neglect plants to test their toughness.
I didn’t do anything to the ZZ in my office (for the past 16 months). Let me tell you – It looks pretty good considering… ready for this – drum roll please – watered only 6 times in 16 months.
Of all the ZZ’s great attributes:
- It’s toughness
- Ability to handle low light
- Low watering requirements
Its best attribute bar none… no insect problems. Or none anyone can identify.
Eliminating this one element makes caring for your plant much easier. The plant leaves you with only a couple of things to manage – light and water, making care easier.
When Should You Water A ZeeZee Plant?
How often to water a ZeeZee?
From my experience give the plant a thorough watering every 10-14 days.
By thorough, I mean soaking the entire rootball and allowing all the excess water to drain out.
Another option is to plant the ZZ up into a SIP – sub-irrigation planter.
How Do You Clean The Leaves On The Zee Zee?
The green leaves of the ZZ are naturally glossy and shiny. No need to apply any type of leaf shine (we don’t recommend them anyway).
Every week or two using a soft damp cloth or damp mircofiber cloth wipe the dust off the leaves. This helps the plant get all the light available and “breathe.”

How Big Do ZZ Plants Get?
The average “Eternity Plant” in a 10″-inch pot will grow to approximately 24″-36″ inches with an equal spread. Growing from a small 4″-inch pot found in many garden centers to a 36″-inch tall plant can take years.
I have a Zamioculcas about 3′ feet tall growing outdoors on a shaded patio with no direct sunlight, living in a 10″-inch pot for over 8 years.
I have seen very old, ZeeZee plants in 17″-inch pots reach 4′ feet in height.
Repotting Your “Steel Plant”
ZZ plants can grow and live in a container for a long time without the need for repotting.
- Repot Zamioculcas in spring
- Using a pot one size larger than the current container. Make sure the pot has drainage holes. Example: 4″-inch to 6″-inch
- Use a good quality soil mix like an African Violet potting mix.
- Fill the bottom of the container with soil.
- Remove the plant from the old pot.
- Remove bad soft or mushy rhizomes
- Place plant in the new pot on top of the soil at the same depth it was previously growing
- Add potting medium and fill in the open space in the pot with soil. Do not “pack” soil
- Water plant thoroughly until water drains out the bottom of the container
- Allow any excess water to drain
- Move the plant to its growing location away from direct light.
- Never allow the plant and pot to sit in water.

Does The “ZZ Plant” Flower?
Yes, the ZZ emerald gem does flower and the “bloom” looks much like a Philodendron or Monstera flower.
