Aloe polyphylla
I discover the inconstant nature of the plant world fascinating. I’ve by no means checked out a rose and wished that the entire leaves grew equally spaced like some AI-generated image of nature.
Or {that a} Japanese maple was completely symmetrical. I feel the irregular gaps in a ginkgo tree that permit the daylight shine by are simply as stunning because the densely packed branches and I wouldn’t want them away.
However the exact association of the leaves of spiral aloe (Aloe polyphylla) displays the unbelievable complexity of the pure phrase. There’s one thing so satisfying about its geometric form.
I say “one thing,” however little doubt its pleasing association speaks to the innately interesting form of the golden ratio and Fibonacci sequence present in nature.
The “golden ratio” is a mathematical ratio the place one portion is precisely half the size of the longer portion.
We hyperlink to distributors that will help you discover related merchandise. Should you purchase from one in every of our hyperlinks, we might earn a fee.
This ratio is related to magnificence and concord and is echoed in artifical artwork and structure. The Fibonacci sequence illustrates this ratio.
It’s exhausting to discover a plant that extra clearly illustrates these ideas in nature than the evenly-spaced progress sample of spiral aloe.
Now, clearly, I’d by no means play favorites with my succulents any greater than a guardian would declare they’ve a favourite youngster.
However the many-leaved aloe, because it’s additionally identified, is unquestionably on the high of my listing. If I might solely save one succulent in my backyard, you recognize which one I’m choosing.
On this information, I’ll offer you some goal information about caring for this placing plant, however I’m not going to try to fake that I’m not fully obsessed by it!
Right here’s what we’ll focus on, sprinkled with numerous admiration:
I don’t learn about you, however I like understanding the historical past of the crops I develop. Typically it helps me perceive extra about the right way to look after them, and typically it’s simply attention-grabbing info.
So earlier than we begin digging into care, let’s have a look at the way it bought from its African house to our properties and gardens.
What Is Spiral Aloe?
Should you head to the cool, moist mountains of Lesotho in southern Africa at elevations from about 6,500 to eight,500 toes, you’ll discover spiral aloes rising on the basalt cliffs, slopes, and rocky areas within the Drakensberg and Maluti mountain ranges.
That’s the one place in the entire world the place they are often discovered indigenously, although they’ve naturalized in areas with comparable climates.
The crops solely develop in spots that face in the direction of the equator and are constantly moist, with wealthy soil.
Sadly, the plant has been overharvested within the wild and is now uncommon in its unique house.
On high of that, the malachite sunbird (Nectarinia famosa) that helps pollinate this aloe within the wild is experiencing a discount in numbers, which doesn’t assist the state of affairs.
The species identify polyphylla means many-leaved. Poly is Greek for a lot of, and phylla is Greek for leaves, which is becoming for this plant. It doesn’t have a stem however as an alternative numerous thick, succulent, pointed leaves.
5 rows on every plant, to be precise, and every row can have as much as 30 leaves.
These spirals progressively increase clockwise or counter-clockwise to type these 5 rows of fats, gray-green, serrated leaves with purple spiky suggestions.
At maturity, which may take as much as a decade, the plant sends up a thick, tall, branched inflorescence with yellow, crimson, or salmon flowers. As soon as these fade, seeds develop.
A mature plant may also begin to cut up. I feel it’s tremendous attention-grabbing when this occurs, as a result of as an alternative of 1 single origin level of the spiral, the aloe will develop two origin factors the place the spiraling rows emerge from.
You possibly can separate these or depart them in place and the plant will finally divide itself in two.
These crops can attain between three and 4 toes vast and a foot tall earlier than they start to separate.
As a result of they’re from a comparatively cool a part of the world, A. polyphylla can tolerate cooler temperatures than many different aloe species. They’re hardy in Zones 7 to 11.
Spiral Aloe Propagation
I first noticed this plant because the background of a good friend’s laptop display and I used to be smitten.
I went on a mission to search out one in every of my very own and it took a very long time. After all, this was a long time in the past and there have been fewer choices on the market.
Lately, numerous retailers carry stay crops and you probably have entry to a mature plant you may harvest seeds.
Many aloes ship out pups or offsets, and you’ll propagate these. Spiral aloe is technically able to placing out offsets, but it surely’s not frequent and so they don’t appear to outlive nicely after transplanting.
Should you do have some offsets that you simply’d prefer to transplant, learn our information for suggestions.
Not like many succulents, you may’t propagate the leaves of spiral aloe.
Should you’re fortunate sufficient to have entry to a stay plant or a good seed vendor, learn on to be taught extra about beginning these crops from seed.
From Seed
You possibly can propagate spiral aloe from seed, however remember that some on-line sellers will mislabel the seeds. Search for respected sellers who present examined and confirmed seeds.
Even respected sellers might typically have seeds that produce crops which might be “confused.” Meaning the leaf sequence gained’t develop within the sample you’re anticipating.
They could be stacked or staggered fairly than spiraled. Some crops will appropriate their progress as they mature.
Since these crops not often flower in cultivation, sourcing viable seeds could be troublesome.
It’s worthwhile to floor sow the seeds and preserve them in temperatures between 60 to 70°F. The medium ought to be stored moist always. Wait till the plant has no less than six true leaves earlier than transplanting.
To be taught extra about the right way to begin aloe from seed, learn our complete information.
From Divisions
As talked about, spiral aloes naturally start to separate into two crops as they age.
You possibly can make the most of this phenomenon to divide your plant into multiples. As soon as the plant has cut up and has two distinct factors of origin within the spirals, you may cut up it up.
To do that, you’ll dig up the plant and brush away the soil. Search for the spot the place the crops are separating and gently tease them aside. Then, replant every part.
Learn our information to dividing aloe for extra recommendation.
I like to recommend you put on lengthy sleeves and gloves when working with this plant as a result of the factors on the leaves could cause damage.
From Transplants
Watch out about the place you buy your plant, as whereas it’s unlawful to reap them from the wild, poachers nonetheless take away them and provide them on the market.
Make sure that your vendor is sourcing them from a good grower.
When they’re younger, the crops don’t but have the distinct spiral formation.
This comes with age, so don’t panic if the one you discover on the retailer or obtain within the mail doesn’t appear like the gracefully spiraling ones you see in footage. That may include time.
When you will have your plant, both seize a pot about the identical measurement or one measurement up from the present rising container.
Or in case you are planning to develop your specimen outside, dig a gap within the backyard concerning the measurement of the rising container.
In case you have considerably heavy soil, dig a gap 3 times the width and twice the depth of the container, and work in equal components well-rotted compost into the eliminated grime.
You may also add some lava rock or perlite to facilitate drainage. Backfill the outlet with the combination, leaving a small gap the scale of the rising container for planting.
Gently take away the plant from its pot by squeezing the perimeters, letting the soil fall away from across the plant’s roots.
Fill the brand new container with a succulent potting combine in order that the spiral aloe can be sitting on the similar top it was within the earlier container.
Set the plant in place and fill in across the roots with extra succulent potting combine, or soil if you happen to’re transplanting into the backyard.
Gently press the medium or soil and add extra if essential.
The best way to Develop Spiral Aloe
Spiral aloe wants a full to partial solar location to thrive. It prefers coolish climates, so if you happen to stay someplace with very excessive temperatures, plant it someplace with afternoon shade to guard it from the most well liked time of the day.
If you’re rising yours as a houseplant, present 4 to 6 hours of direct solar per day. Meaning a south- or west-facing window is good.
These crops do their rising when temperatures are between 50 to 80°F, however they’ll tolerate a freeze.
Should you stay in Zone 7, you may need to cowl the plant in frost fabric if it isn’t lined in snow, simply to be secure.
Don’t overwater your spiral aloe. I’m telling you, overwatering will shortly end in root rot, and it occurs to so many aloes and different succulents.
Let the bottom or potting medium dry out fully between watering. Every time earlier than you water, stick a finger within the soil. It ought to really feel dry as deep as you may attain.
Within the winter, the plant goes semi-dormant and requires even much less water than it does through the rising season. Let the soil dry out for per week or two earlier than you water once more.
Should you’re rising outside, add some perlite or lava rock to the soil to assist loosen it up.
For container-growing, select a well-draining succulent or cactus medium.
Alternatively, you may make your individual succulent potting combine. Spiral aloe prefers barely acidic to impartial soil with a pH of 5.5 to 7.0.
I like Tank’s-Professional Cactus & Succulent Combine, with its good combination of pumice, coco chips, and natural compost.
Tank’s-Professional Cactus & Succulent Combine
Arbico Organics carries this combine in one-and-a-half cubic foot luggage.
Talking of containers, select one that’s produced from wooden, ceramic, or terra cotta to stop the soil from overheating. If the soil temperature rises above 80°F it might kill your aloe.
The last word measurement of the container will should be extraordinarily massive if you would like your aloe to spiral out as massive as it will probably.
Relying on the scale of the specimen you can begin it in a smaller container, clearly, however you’ll finally must improve to one thing doubtlessly as massive as a half barrel that may maintain over 20 gallons of soil to accommodate a mature plant. This could occur in about seven years.
Containers are a wonderful possibility for these of us who’ve heavy, clay soil in our gardens.
Don’t feed out of doors crops. These rising indoors could be fed as soon as within the spring with a slow-release cactus fertilizer or as soon as in spring, summer season, and fall with a typical fertilizer. Don’t use granular fertilizer.

Don’t anticipate the distinctive spiral sample to develop till the plant has 45 leaves – 5 rows of seven leaves. That’s when the sample turns into apparent.
Rising Suggestions
Develop in full solar with afternoon shade in scorching climates.
Permit the soil to dry out fully between watering.
Feed in spring with a slow-release meals or as soon as in spring, summer season, and fall with a typical meals.
Upkeep
If any of the leaves change into diseased, flip yellow or brown, or break, don’t take away them.
Wait till they dry up and detach naturally. Pulling or slicing off broken or discolored leaves could cause extra hurt than good.
I do know it’s not fairly, however resist the urge to get in there and clear issues up till the leaf could be pulled away with out having to tug it.
Consider spiral aloe because the anti-maintenance plant. Give it the circumstances it prefers and let it’s.
As your aloe grows and reaches the perimeters of its container, you’ll need to repot your aloe into a bigger pot.
Take away the plant from its container, discard all the surplus soil, and put a layer of cactus and succulent potting medium within the new container.
Set the plant in place and fill in across the roots with extra potting medium.
The place to Purchase
This plant has been overharvested within the wild and is in peril of extinction.
Be tremendous cautious when buying and be sure to discover a respected vendor that doesn’t promote poached crops or seeds.
You’ll probably discover spiral aloe obtainable at specialty nurseries, particularly these that target succulents and xeriscaping.
Managing Pests and Illness
Harassed spiral aloe crops are extra vulnerable to issues, significantly from pests, than these which might be joyful.
Maintaining the plant in the precise circumstances and offering the precise care will go a great distance in the direction of avoiding issues with pests and illness.
That mentioned, even one of the best cared-for plant can face points. Let’s speak about a couple of pests that like to snack on spiral aloe.
Pests
Aloe mites are devastating pests that do plenty of harm and are unimaginable to get rid of. Let’s speak about these, first.
Aloe Mites
An in depth relative of spider mites, aloe mites (Eriophyes aloines) infest the highest of the roots of aloe crops the place the leaves emerge.
Once they feed, they trigger the plant to break down, which may usually be mistaken for root rot, which we’ll focus on beneath. The larvae can solely be seen with a magnifying glass, so it may be exhausting to inform they’re current.
You’ll must test the roots to see in the event that they’re rotting and search for the grownup mites, which you’ll see crawling round if you happen to use a hand lens.
If the plant has a mite infestation, there is no such thing as a remedy and also you’ll must eliminate the plant to stop the mites from spreading.
Aphids
Whereas there could be a number of completely different aphid species that feed on aloes, aloe vera aphid (Aloephagus myersi) is the key participant in California and Florida.
They haven’t but been reported outdoors of those areas on the time of writing.
Whatever the species, all aphids are sapsucking bugs that cluster and feed on plant tissue.
They like to cover in protected areas, which makes it exhausting to identify them on spiral aloes, as a result of there are such a lot of nooks and crannies in between the leaves.
Greater than probably, it’s the harm you’ll see fairly than the pests themselves. As they use their sucking mouthparts, they drain sap, leaving speckled yellowing on the leaves.
You may additionally see sticky honeydew, which is basically aphid poop, and the darkish, black fungus referred to as sooty mould that’s interested in the honeydew.
In case your specimen has an aphid infestation, you’ll must saturate the plant in insecticidal cleaning soap as soon as each few weeks, taking care to get into the folds in between the leaves.
Bonide Insecticidal Tremendous Cleaning soap
I like to make use of Bonide Insecticidal Tremendous Cleaning soap, which is offered from Arbico Organics in quart-sized, ready-to-spray bottles. Comply with the producer’s instructions for software.
Springtails
Springtails are tiny bugs that feed on fungi and decaying roots within the soil.
They want excessive moisture within the soil to thrive, in order that they shouldn’t often be an issue if you happen to’re letting the soil dry out fully.
They don’t often trigger a lot harm, however their presence is a sign that the circumstances are all improper to your spiral aloe.
Scale back watering or cowl your plant if it’s the wet season. Once you appropriate the atmosphere, the springtail downside will resolve itself.
Illness
Root rot is a standard and lethal downside in all sorts of aloes. It has two causes. The primary is solely drowning the roots in a lot water that they’ll’t breathe.
The opposite is fungal pathogens within the Fusarium genus, that are interested in moist soil. Both approach, an excessive amount of water is the principle driver.
When root rot units in, the ideas of the leaves will flip black. The roots can be brown, comfortable, and mushy. Should you suspect root rot, take away the plant from the container and spray off the soil from the roots.
Really feel the roots and take away any which might be fully mushy. Those who really feel a bit agency can often be saved.
Scrape off any useless materials from the skin of the roots utilizing a knife. You need to reveal the agency, yellow tissue beneath.
Replant and don’t water once more till you may gently wiggle the plant and it stays in place fairly than wobbling, indicating it has developed new roots.

You don’t want multiple spiral aloe to make a big effect, however you would actually group three or 5 for a wow issue.
In any other case, let it take centerstage in a succulent backyard. You possibly can develop it inside as a houseplant you probably have sufficient gentle or outdoors in a container.
