About Raven ZZ Plant

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

A striking cultivar of the classic ZZ plant whose new leaves emerge bright lime-green then gradually deepen to near-black as they mature, creating a dramatic two-tone effect. Exceptionally drought-tolerant thanks to water-storing rhizomes, it thrives in low light and suits almost any indoor environment. Slow-growing but nearly indestructible.

Comfort temperature: 15–30°C

Watch for — Slow colour darkening: New leaves emerge green and take several weeks to mature to near-black — this is normal for the Raven cultivar. Ensure the plant receives adequate indirect light, as very low light can slow the darkening process.

The exact light raven zz plant needs

Raven ZZ Plant is famous as a "low light" plant — but that means it tolerates dim rooms, not that it prefers them. It survives a north corner; it grows better with more light.

Put a number on it — this is what a meter (or a free phone light-meter app) should read where raven zz plant sits:

In plain terms, Honestly, bright indirect light if you have it — raven zz plant grows fastest there. But it is one of the very few that genuinely cope in a north room, an interior wall, or a few metres from any window. Direct hot sun (it is adapted to shade and scorches), and total darkness — even a tough plant needs some daylight; a windowless room with the light off all day will eventually kill it.

Signs raven zz plant is getting too much light

The most exposed leaves show it first. For raven zz plant specifically, watch for:

Light damage does not heal — a scorched leaf stays scorched — so the fix is to move raven zz plant out of the harsh light rather than wait for it to recover.

Signs raven zz plant is not getting enough light

Too little light is slower and sneakier than too much. The classic tell is etiolation: the plant stretches and pales as it reaches for a window. For raven zz plant, look for:

If raven zz plant is stretched, leggy and pale, our guide to leggy, stretched plants covers how to fix it and whether it can be pruned back into shape. Believing "low light" means "no light", then overwatering it. In a dim spot raven zz plant barely grows and barely drinks — so the usual watering schedule drowns it. Far more low-light plants die from rot than from darkness. Treat the dim spot as the cap on watering, not just on growth.

Where to put raven zz plant: the best window and room

Raven ZZ Plant is the plant for the spots nothing else survives: a north-facing room, an interior hallway, a desk away from the window, a dim bathroom. It will live there. But if you want it to actually grow and look its best, give it bright indirect light — it is tolerant of low light, not fond of it. Keep it out of direct sun, which it has no defence against.

  1. Place it where nothing else copes. Raven ZZ Plant is ideal for a north room, interior wall or dim corner — spots that would slowly kill most houseplants.
  2. Still give it some daylight. "Low light" is not "no light": keep raven zz plant within sight of a window or under regular room lighting, never in a permanently dark room.
  3. Cut watering to match the dimness. In low light raven zz plant barely drinks — let the soil dry much more than usual, because rot, not darkness, is what kills it here.
  4. Add a small grow light to thrive. To move raven zz plant from surviving to thriving in a dark room, a modest LED grow light 10–12 hours a day is enough — it does not need a powerful fixture.

Does raven zz plant need a grow light?

A grow light transforms raven zz plant in a dark room — and because it is not a high-light plant, even a modest full-spectrum LED on a timer for 10–12 hours a day takes it from "just surviving" to genuinely thriving. It is one of the most rewarding species to add a small light to in a windowless space.

The seasonal light shift (why winter changes everything)

The trap with a low-light plant in winter is water, not light. Raven ZZ Plant already grows slowly; from November to February it nearly stops, so cut watering right back — the soil will stay wet for weeks. Move it as close to a window as you can for the dim months, hold off all feeding, and resume normal care only when spring growth restarts.

Light and watering are linked: a plant in weaker winter light photosynthesises and drinks far less, so the same routine that worked in summer can rot it. See how often to water raven zz plant for the season-by-season schedule that pairs with this light plan.

Raven ZZ Plant light requirements — frequently asked questions

How much light does raven zz plant need?

Raven ZZ Plant needs Survives down to ~50–75 fc; grows well at 150–400 fc. The low end is its tolerance floor, not its happy place. Tolerates ~500–800 lux; does noticeably better at 1,500–4,000 lux. Honestly, bright indirect light if you have it — raven zz plant grows fastest there. But it is one of the very few that genuinely cope in a north room, an interior wall, or a few metres from any window.

Can raven zz plant survive in low light?

Yes — raven zz plant is one of the genuinely low-light-tolerant plants: it survives a north room or dim corner. But "tolerates" is not "prefers" — it grows faster and looks better in bright indirect light, and the real danger in a dim spot is overwatering, not the darkness itself.

What are the signs raven zz plant is getting too much light?

Yellowing, bleached or scorched leaves if raven zz plant is moved into direct sun — it is a shade-adapted survivor, and harsh light burns it surprisingly fast. Pale, washed-out colour where the sun hits, while shaded leaves stay rich and dark. Crispy brown patches after a move from a dim shop straight into a hot window. Believing "low light" means "no light", then overwatering it. In a dim spot raven zz plant barely grows and barely drinks — so the usual watering schedule drowns it. Far more low-light plants die from rot than from darkness. Treat the dim spot as the cap on watering, not just on growth.

What are the signs raven zz plant is not getting enough light?

Very slow or completely stalled growth — the honest sign raven zz plant is at its light limit (it will not dramatically die, it just stops). New leaves come in small, spaced far apart and leaning hard toward the nearest window — etiolation, even in a "low light" plant. Soil stays soggy for weeks after watering because the plant is barely drinking — the real danger here is overwatering a low-light plant, not the light itself. If you see this, move raven zz plant closer to the light or add a grow light — and check our guide on leggy, stretched plants.

Does raven zz plant need a grow light?

A grow light transforms raven zz plant in a dark room — and because it is not a high-light plant, even a modest full-spectrum LED on a timer for 10–12 hours a day takes it from "just surviving" to genuinely thriving.
