Alocasia Sarian Albo is the white-sectored form of Alocasia 'Sarian', a Philippine Alocasia with a well documented arrival in cultivation and a still unsettled botanical status. This guide covers where the plant comes from, what is and is not known about its parentage, what albo variegation means on a plant like this, and how to look after it.
What is Alocasia 'Sarian'?
Aroidpedia, the main reference we use for aroid naming and history, describes Alocasia 'Sarian' as an undescribed species from Ilocos Norte, a province on the island of Luzon in the northern Philippines. It has no formal species name, which is why it is written in quotation marks as a cultivar-style name. Aroidpedia lists no cultivars under it, and the albo form is not documented there; what is specific to the albo sectors in this guide comes from how chimeric variegation works in general and from our own experience of growing this plant.
Aroidpedia also notes that the plant has been photographed growing in situ in Quezon, on Luzon, and that it grows alongside Alocasia micholitziana at around 850 metres, which it gives as the upper limit of its altitude range. The climate it records there is moderate: humidity of 60 to 70 per cent, with temperatures from roughly 9 to 31°C and minimums staying above about 7°C. That is a useful guide to what the plant is comfortable with in a UK home.
Origin and naming: who was Sarian?
The name honours Zacarias 'Zac' Bolong Sarian, a Filipino agricultural journalist who wrote for the Manila Chronicle in the 1960s and later edited Philippine Farms and Gardens. According to Aroidpedia, in the early 1980s a Singaporean buyer asked him to survey Aglaonema in the Philippines. During that work a plant trader delivered offshoots of what became this plant. Visitors from the Australian chapter of the International Aroid Society then bought propagations from him and later wrote about the find in Aroideana, which is how it reached collectors more widely.
Is it a hybrid? Parentage explained
You will often see 'Sarian' described as a hybrid of Alocasia zebrina and Alocasia micholitziana. Aroidpedia records that no parentage is documented and that this hybrid claim is only an assumption, one that Zac Sarian himself disputed. His reasoning was that the plant appears to be indigenous and widespread, with a range that does not overlap with the suspected parents.
The taxonomy is still open. Aroidpedia reports that in 2020 the Philippine botanist Fernando Biglang-awa Aurigue said it was still treated as a variety of Alocasia macrorrhizos, because of similarities in the flowers and its presence in Ilocos Norte, and that a group was carrying out genetic studies to settle the question. Until that work is published, it is most honest to call it an undescribed species of uncertain placement. Species, natural hybrid or something else entirely, it is botanically distinct from the plants it is most commonly alleged to descend from. If you want to read about the plants it is compared with, see our Alocasia macrorrhizos species guide.
How to identify Alocasia 'Sarian'
Aroidpedia gives little in the way of a general description, and no leaf or plant dimensions; the sizes below come from our own growing instead. What it does offer is a comparison with A. micholitziana, which is the plant most often confused with it. The leaf of 'Sarian' is described as thinly rubbery rather than velvety, the margins are shallowly undulate rather than deeply sinuate, and the petiole joins the blade at the junction of the posterior lobes rather than sub-peltately. Those three points are a more reliable way to tell the two apart than overall appearance, which varies with light and age.
From cultivation rather than from Aroidpedia, the plant is one of the more dramatically scaled Alocasia in common collection. In good conditions a leaf can reach 40 to 50cm and may exceed 60cm in optimal conditions, with the whole plant reaching 120 to 180cm or more; in UK indoor cultivation a well-managed Sarian typically reaches 60 to 90cm, with leaves of 30 to 45cm. The leaves are broadly arrow-shaped and intensely dark green, already carrying prominent white to cream venation before any white sector appears, and the long, slender petioles are marked with a distinctive zebra-like striping that connects visually to the zebrina lineage often cited as a parent.
What albo variegation looks like on this plant
Albo variegation means white sectors in which the cells carry no chlorophyll. The pattern is chimeric: the white tissue sits in layers or sectors alongside normal green tissue, so each leaf is different and the proportion of white can change from one leaf to the next. White tissue cannot photosynthesise, so every leaf with a large white sector is being supported by its green neighbours. Our guide to albo variegation in Alocasia explains the mechanism in more detail, and the complete guide to variegation types shows how albo differs from aurea, pink and mint.
What distinguishes albo variegation on Sarian specifically is scale. The sheer size of the leaves amplifies the visual impact of every white sector to an extent impossible on compact jewel species: on a compact jewel species a 5cm white sector is a significant visual element, but on a Sarian leaf that might reach 45cm in length a comparable proportion of white tissue operates at a fundamentally different visual scale. The result is broad sweeps of white against dark green, framed by the wavy leaf margins, with the bold white primary venation continuing through both variegated and non-variegated tissue to provide structural continuity. White sectors on a well-variegated leaf read as bold architectural statements rather than delicate colour accents, and together with the zebra-striped petioles and prominent white venation they make a display specimen of considerable presence. Because the margins are wavy, albo sectors at the leaf edge create a particularly dynamic boundary: the white tissue follows the undulation, creating a rippled, organic edge rather than a straight line. The non-photosynthetic sectors also create a meaningful metabolic demand on the green tissue, which is a more significant consideration on a large-leaved plant than on compact species, as each leaf represents a substantial investment of energy to produce.
Because the variegation is chimeric, a plant grown from a corm might not carry the white sectors across. The corm is produced by the plant's own tissue, and which cell layers it contains is not predictable. Treat albo expression on any corm-grown plant as something that will be revealed as it grows, not something guaranteed.
The yellow form is the variegated type that Aroidpedia lists for 'Sarian'. If you are choosing between the two, our Alocasia Sarian Aurea guide covers the golden form.
Alocasia Sarian Albo care
This is general Alocasia care, and it applies to this plant as it does to the rest of our collection. Our ultimate Alocasia care guide goes deeper on each point.
- Light: bright indirect light, supplemented with LED grow lights where the room is dim. Albo sectors contribute nothing to growth, so the green tissue needs plenty of light. The large leaf area means even small reductions in light create relatively large reductions in total photosynthetic output. Our article on whether LED grow lights are worth it sets out the case.
- Temperature and humidity: 20 to 27°C and 60 to 80 per cent humidity. Large leaves have proportionally greater transpiration surface than small ones, so low humidity causes crispy edges on the broad leaf margin more quickly and visibly than on compact species. A heat mat helps if the room runs cool.
- Substrate: Fluval Stratum in a pot that drains freely. Our article on substrate explains the thinking, and substrates and growing media lists the options.
- Watering: water thoroughly when the top 2 to 3cm has dried. Keeping the root zone consistently soggy invites rot; our root rot guide covers prevention and recovery.
- Feeding: our Alocasia feed at half strength, from the plant feed range. A variegated plant has less green tissue to work with, so a gentler approach is sensible. Feed conservatively, at quarter to half strength every 2 to 3 weeks; the albo form's reduced photosynthetic capacity makes it more sensitive to overfeeding.

Propagating Alocasia Sarian Albo from corms
Corms are one of the most economical ways to grow more Alocasia, and the method is the same whatever the cultivar. Our Alocasia corm propagation guide sets out the self-wicking approach step by step: the corm sits in damp Fluval Stratum held in a Corm Keeper, which draws water up to the corm without waterlogging it. Our articles on growing corms in Fluval Stratum and how long a corm takes to sprout cover what to expect. As noted above, albo expression is not guaranteed on a corm-grown plant.
How Alocasia 'Sarian' compares with similar plants
The plant most often compared with 'Sarian' is Alocasia micholitziana, the form better known in collections as Frydek, which grows with it in the wild. Our Frydek variegated guide is a good companion read. The other suspected parent, A. zebrina, is covered in our zebrina aurea guide. For other albo forms you can explore our albo variegated collection, or browse rare Alocasia A to Z.

Alocasia Sarian Albo FAQ
Is Alocasia 'Sarian' a hybrid?
It is often described as a cross between A. zebrina and A. micholitziana, but Aroidpedia records this as assumed rather than documented, and Zac Sarian himself disputed it.
Where does Alocasia 'Sarian' come from?
Aroidpedia gives Ilocos Norte on Luzon, in the northern Philippines, and also records it in situ in Quezon.
Who is the plant named after?
Zacarias 'Zac' Sarian, a Filipino agricultural journalist who was first handed offshoots in the early 1980s.
Is the albo form stable?
Chimeric variegation can shift, and white sectors can reduce or disappear over time or fail to carry across to corm-grown plants. Good light helps maintain healthy green tissue alongside the white.
How big does it grow?
Aroidpedia gives no size for this plant; from our own growing, leaves reach 40 to 50cm and the whole plant 120 to 180cm or more, while in UK indoor cultivation it typically reaches 60 to 90cm. Growth depends on light, feeding and pot size.
Is Alocasia Sarian Albo toxic?
Like other Alocasia, all parts contain calcium oxalate crystals and are harmful if eaten, and the sap can irritate skin. Keep it away from pets and children.
