ZZ Plant Varieties: Standard, Raven, Zenzi, and the Rest of the Zamioculcas Family

First: every ZZ variety is one species

Zamioculcas is a monotypic genus — there's only one species, Zamioculcas zamiifolia. Every ZZ plant variety in the houseplant market is a cultivar of that one species, selected by growers for a specific visual feature: leaf colour, plant size, leaflet shape. There's no "black ZZ species" or "dwarf ZZ species" — they're all the same plant with different selected traits, like Granny Smith and Pink Lady are both Malus domestica.

This matters for ID because most varieties look so different from each other that beginners assume they're unrelated. Once you know they're one species, the question becomes "which cultivar?" — answered by leaf colour, mature height, and leaflet shape. Care is identical across all of them.

The 10-second variety test

Look at the colour of mature leaflets, the overall plant size, and the leaflet shape.

• 1Mature leaflets are jet black or very dark purple-black? → 'Raven' (also sold as 'Dowon').
• 2Leaflets are glossy mid to dark green, plant is 60–100 cm tall? → Standard Zamioculcas zamiifolia.
• 3Plant is compact (under 40 cm), with short stems and tight overlapping leaflets? → 'Zenzi'.
• 4Plant is small (30–50 cm), with rounder, more spoon-shaped leaflets? → 'Lucky Classic' or 'Akebono'.
• 5Leaflets have irregular cream-and-green variegation? → 'Variegata' or 'Lucky White'.

Standard ZZ — Zamioculcas zamiifolia

The wild-type Zamioculcas zamiifolia produces arching upright stems (technically pinnate compound leaves, but most people call them stems) with paired glossy oval leaflets running along the length. A mature plant in a 25 cm pot reaches 60–100 cm tall and 50–80 cm wide. The leaflets are mid to dark green, thick, glossy, and slightly waxy — they look almost artificial, which is part of what makes the plant so popular as a low-effort decor object.

Underground, ZZ stores water in large potato-like rhizomes, which is what makes the plant so drought-tolerant — it can survive months without water once established. New stems emerge tightly furled from the rhizome and unfurl over a few days into the characteristic feathery shape. Native to dry regions of eastern and southern Africa, the plant evolved to handle long dry seasons, which is why overwatering kills more ZZs than any other cause.

• ·Leaflet: glossy oval, mid to dark green, paired along stems.
• ·Stem: arching upright, 60–100 cm long.
• ·Mature size: 60–100 cm tall, 50–80 cm wide.
• ·Underground: large potato-like rhizomes that store water.
• ·Native: eastern and southern Africa (Kenya, Tanzania, South Africa).

'Raven' ZZ — the jet-black cultivar

'Raven' (sometimes sold as 'Dowon') was patented by a Korean grower around 2018 and has become one of the most-hyped houseplants of the last few years. New growth emerges bright lime green and gradually darkens over 4–6 weeks to deep purple-black. A mature 'Raven' has stems with both green new leaflets at the tip and black mature leaflets along the lower portion — the contrast is striking.

Care is identical to standard ZZ — same drought tolerance, same low-light tolerance, same slow growth. The only practical difference: 'Raven' produces less chlorophyll per leaf area than green varieties (because of the dark pigment), so it grows slightly slower and benefits from the brighter end of "bright indirect" light. In low light it stays alive easily but produces few new stems.

• ·Leaflet: emerges lime green, matures to jet black or deep purple-black.
• ·Stem: same arching upright form as standard ZZ.
• ·Mature size: similar to standard, 60–90 cm tall.
• ·Slightly slower-growing than standard.
• ·Patented cultivar — relatively new (2018+); often sold at premium price.

'Zenzi' — the compact dwarf

'Zenzi' is a naturally compact mutation of standard ZZ, with stems that stay much shorter (typically 20–40 cm) and leaflets clustered tightly together along the stem. The result is a plant that looks like a smaller, denser, more sculptural version of the standard — perfect for desks, shelves, and small windowsills where a full-size ZZ would be too large. Mature 'Zenzi' rarely exceeds 40 cm tall and 30 cm wide.

Leaflets are the same glossy green as standard ZZ but appear darker because they're so densely packed. New growth emerges from the rhizome the same way as standard, just shorter. 'Zenzi' is fully drought-tolerant and survives the same neglect as the parent species — it's an excellent pick for someone who wants a ZZ but doesn't have floor space.

• ·Stem: short (20–40 cm), much more compact than standard.
• ·Leaflet: same glossy green, but tightly clustered along the stem.
• ·Mature size: 30–40 cm tall, 25–35 cm wide.
• ·Habit: dense and sculptural — looks like a miniature standard ZZ.
• ·Patented cultivar; harder to find than standard but increasingly common.

'Lucky Classic', 'Lucky White', and the Lucky series

The "Lucky" series is a group of compact ZZ selections with smaller, rounder, more spoon-shaped leaflets than the standard. 'Lucky Classic' is the original — green leaflets, more rounded than standard, plant size around 30–50 cm. 'Lucky White' has irregular cream-and-green variegation, similar to 'Variegata' but on the smaller compact frame.

These cultivars sit between standard ZZ and 'Zenzi' in size and have a slightly softer-looking foliage than the standard. They're often sold without the cultivar name on the label, just as "compact ZZ" or "dwarf ZZ" — distinguishing them from 'Zenzi' takes a close look at leaflet shape (Lucky leaflets are more rounded; Zenzi leaflets are more conventionally oval but tightly packed).

• ·'Lucky Classic': compact, rounded leaflets, all green, 30–50 cm.
• ·'Lucky White': compact with cream-and-green variegation.
• ·'Lucky Giant': larger version of Lucky Classic, intermediate size between Lucky and standard.
• ·Often sold at general garden centres unlabelled as "compact ZZ".
• ·Identify by rounder, spoon-shaped leaflets vs the standard's oval shape.

'Variegata' and 'Akebono' — the variegated cultivars

Variegated ZZ plants are rare, expensive, and slow-growing — the variegation reduces chlorophyll, which slows growth dramatically. 'Variegata' has irregular cream and green panels distributed unpredictably across the leaflets; some leaflets are mostly green, others mostly cream, and some have sharp boundaries between the two. Each plant is unique because the variegation pattern doesn't predict.

'Akebono' is a Japanese-bred cultivar with a more refined variegation pattern — light yellow-green and dark green stripes on a smaller, more upright plant. Both 'Variegata' and 'Akebono' need the brightest indirect light a ZZ can tolerate (still no direct sun) to keep the variegation strong; in low light they revert greener over time.

• ·'Variegata': irregular cream-and-green panels, unpredictable distribution.
• ·'Akebono': lighter yellow-green and dark green stripes, more refined pattern.
• ·Slowest-growing varieties of ZZ — often half the speed of standard.
• ·Need brighter indirect light to maintain variegation.
• ·Rare and expensive; mostly available through specialist growers.

Care is identical across all varieties

Every ZZ variety wants the same conditions: bright indirect light (tolerates low light, grows slowly), thoroughly dry soil between waterings (the rhizomes store water for weeks), well-draining mix, and minimal feeding. The dark and variegated varieties ('Raven', 'Variegata', 'Akebono') benefit from slightly brighter light to compensate for less chlorophyll, but none of them want direct sun — leaves scorch quickly.

Watering is the only place to be careful. ZZ rhizomes rot fast in wet soil; underwatering is rarely fatal, overwatering frequently is. Wait until the soil is bone dry several centimetres down before watering thoroughly. In winter, this can mean every 4–8 weeks; in summer, every 2–4 weeks. Yellowing lower leaflets that drop off easily is the classic overwatering symptom — see our watering guide and root rot guide for diagnosis.

All ZZ varieties are mildly toxic to pets

Every Zamioculcas zamiifolia cultivar contains insoluble calcium oxalate crystals in its leaves and stems, which cause mouth and throat irritation, drooling, and vomiting if chewed by cats or dogs. The crystals also irritate human skin in some people during repotting — wear gloves if you're sensitive. Reactions are usually mild and self-limiting.

ZZ leaves are firm and slightly bitter, so chewing is uncommon even when accessible — most pets try a leaf once and lose interest. But the plant should still be kept out of reach of pets that habitually nibble greenery. See our pet-toxicity guide for non-toxic alternatives.

Common nursery mislabels

ZZ plants are often sold unlabelled as just "ZZ plant" or "Zamioculcas" with no cultivar name. The visual chart above identifies what you actually have.

• ·Standard ZZ is sometimes labelled "Zanzibar Gem" — same plant.
• ·'Zenzi' is often confused with 'Lucky Classic' — Zenzi has standard-shaped leaflets densely packed; Lucky has rounder spoon-shaped leaflets.
• ·Variegated ZZ at general garden centres is usually 'Lucky White' or 'Variegata' — both names refer to similar irregular cream-and-green patterns.
• ·'Raven' is occasionally mislabelled as a separate species ("Black ZZ" or "Black Zamioculcas") — it's the same species (Z. zamiifolia) selected for dark pigment.
• ·Run a photo through a plant ID app for unusual cultivars; standard, Raven, and Zenzi are all in major training datasets.

Choosing the right ZZ variety

If you want the classic look and the best price, the standard Zamioculcas zamiifolia is unbeatable — widely available, fast-growing for a ZZ, and the most forgiving of low light. If you want drama and have a brighter spot, 'Raven' is the standout — the jet-black foliage is unique among houseplants and reads as intentional decor in modern interiors. If you don't have floor space, 'Zenzi' delivers the same look in a desk-friendly package.

The Lucky series is a good middle ground — smaller than standard but less compact than Zenzi, with a softer leaflet shape. Avoid the variegated cultivars unless you want a slow-growing, expensive, attention-demanding plant — they're beautiful but they're not the easy ZZ everyone else has.
