About ZZ Plant Raven

Zamioculcas zamiifolia 'Raven' · also called Raven ZZ Plant, Black ZZ Plant · houseplant

ZZ Plant 'Raven' is a dramatic cultivar of Zamioculcas zamiifolia whose new leaves emerge bright lime green then mature to a deep, glossy near-black purple. It keeps the species' famous toughness, storing water in fat underground rhizomes to survive drought and low light, making it a striking, almost indestructible statement houseplant.

Mature size: About 60-90 cm tall and wide indoors, growing slowly over several years.

Watch for — New growth reverting green: Fresh foliage is naturally lime green and darkens with age and adequate light. If leaves stay pale and never blacken, increase bright indirect light.

Indoor size vs how big it gets in the wild

ZZ Plant Raven stays fairly low but widens over time — it spreads into a bigger clump by offsets, runners or rhizomes rather than shooting upward. Indoors and in a pot, expect about 60-90 cm tall and wide indoors, growing slowly over several years.. A pot, your light levels and a little pruning are what set the final size in a home, far more than the plant's theoretical potential.

Size here is about width, not height: the plant builds an ever-wider clump or sends out plantlets and runners while staying relatively short.

Growth rate and years to mature

ZZ Plant Raven is a slow grower. Realistically, expect many years — it gains very little each season, so it can hold the same shelf-sized footprint for 5-10+ years. Its feeding profile backs this up: feed with a balanced houseplant fertiliser at half strength once a month during spring and summer. 'raven' is a slow grower, so avoid overfeeding, which causes salt buildup and leaf-tip burn.

Want this turned into the right next pot at the right moment? The pot size calculator and the zz plant raven repotting guide cover when and how much to size up — pot size is one of the biggest levers on how fast zz plant raven grows.

How to keep zz plant raven smaller

You are not stuck with the maximum size. For zz plant raven specifically, these are the levers, in order of impact:

Divide the clump every year or two — splitting zz plant raven is the main way to control its spread and refresh it.
Remove runners, plantlets or offsets as they appear if you want it to stay a single tight clump.
Keep it slightly pot-bound; a snug pot naturally limits how wide the clump can get.

The keep-it-smaller method, step by step

Lift the whole plant. Slide zz plant raven out of its pot in spring when the clump has filled it.
Split the clump. Tease or cut the rootball into two or more sections, each with healthy roots and growth.
Repot one division. Put a single division back in the original pot to reset it to a smaller size; pot or give away the rest.
Remove offsets as they form. Through the year, detach new runners or pups to stop it spreading again.

How to grow zz plant raven bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for zz plant raven the accelerators are:

Give it a wider pot and let the clump fill it — width is exactly how this plant gets bigger.
Brighter light speeds up clump and offset production noticeably.
Leave plantlets and offsets attached and feed through the growing season for the fastest spread.

Light is almost always the ceiling. The zz plant raven light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When zz plant raven outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for zz plant raven:

The clump bulging over the pot rim or splitting the pot — the cue to divide, not to find a bigger room.
A dense centre that goes bare or tired while the edges keep spreading.
Runners or offsets escaping across the shelf or into neighbouring pots.

If it is the pot rather than the room, it is a repotting job, not a goodbye — see the zz plant raven repotting guide. If you want more of this plant instead of a bigger one, the zz plant raven propagation guide turns prunings into new plants.

How big does zz plant raven get?

ZZ Plant Raven reaches about 60-90 cm tall and wide indoors, growing slowly over several years. when grown indoors. Size here is about width, not height: the plant builds an ever-wider clump or sends out plantlets and runners while staying relatively short.

Is zz plant raven slow or fast growing?
