Alocasia reversa 'Blue Jewel' - 1 Gallon

Alocasia reversa 'Blue Jewel' - 1 Gallon



Alocasia reversa


This rare & unique Alocasia was named for its incredible foliage color. The person who gave it its name felt that this is the only variety that has the reverse coloring of the average Alocasia - with a darker vein color than leaf color, however, some Alocasia enthusiasts would disagree. 


This variety of Alocasia is a member of the Jewel Alocasias. Jewel Alocasia is a term for an Alocasia species thats often small enough to fit in the palm of your hand & displays one of many dazzling colors, shapes & textures. Their small size can be functionally great for terrariums because they will actually fit & have a slow growth rate. However, it is their array of appearances that really make them shine. Some Jewel Alocasia varieties include Alocasia reversa, as well as Alocasia melo, Alocasia 'Red Secret', Alocasia infernalis 'Black Magic,' Alocasia baginda 'Dragon Scale,' Black Velvet Alocasia, Alocasia 'Bambino,' Alocasia 'Imperialis,' & the Grey Dragon Alocasia. 


The leaves on Alocasia reversa are thicker than those on garden-variety Alocasias. This means the Blue Jewel may take a bit more moisture without succumbing to root rot. However, this doesn't mean you shouldn't beware of the dreaded overwatering!! 


In it's native habitat of Borneo (more specifically, Sarawak), Alocasia reversa grows in the forest over stone, often on boulders. Temperatures are best between 60-85ºF. Good soil drainage is essential to keeping Alocasia happy. Fertilizer can be used at 1/4 or 1/2 strength after plants have their roots established.

  • Plant Requirements & Maintenance

    Bright, indirect light
    Avoid direct sunlight! Will burn leaves.
    Outside - partial shade

    The amount of light it receives will dictate how quickly it grows. If you want our plant to push out new leaves actively & produce large leaves, make sure it receives plenty of bright, indirect light. The plant will tolerate, but not thrive, when placed in an area with lower light levels. It will survive, but will not grow as quickly. You can take your Alocasia reversa outside during warmer months, however, make sure it stays far away from direct sunlight. Outside it will prefer partial shade. 


    Water when top 2 to 3 inches of soil is dry. Keep soil evenly & consistently moist, while avoiding stagnant water at the bottom of your pot. Continually soggy soil will prevent the roots from finding any oxygen, which will lead to root rot & other disease. 

    During WINTER months, cut back on watering if plant is not actively growing.


    Loose, nutrient rich potting soil. 

    Soil medium that will retain moisture, but is also well-draining.

    Most pre-mixed potting soils will suffice. Make sure there is plenty of organic matter in your soil, like coco-coir, peat moss, shredded leaves, etc. Avoid soils containing moisture retaining crystals. 

    If soil drains too quickly, repot your Alocasia reversa into a compost-rich soil mixture with fewer drainage materials.


    This is a subtropical plant. Blue Jewel prefers warmer temperatures. 

    Average room temp should be above 60ºF.

    If you take your Alocasia outside during the warmer months, bring it inside if night temps fall below 55ºF. 

    Avoid placing your plant near a drafty window, exterior door, or in front of an air condition or heating vent. temperature fluctuations can inhibit growth & potentially damage the leaves. 

    Although they may not lose all their leaves, they will stop growing & should be kept in slightly lower temperatures during their downtime.


    Alocasia reveersa thrives in heavy humidity, hence its subtropical origins. Place the houseplant in an area with high moisture - your kitchen or bathroom are both naturally humid rooms. if you live in a drier climate or are lacking high humidity in your house, consider using a humidifier or pebble tray. 


    Routine fertilizing during grow months can help plants push out new growth. A diluted complete liquid fertilizer, a fish or seaweed emulsion, or a slow release fertilizer are excellent choices for this variety of Alocasia {we use Osmocote - a slow release option}. Do not fertilize your Alocasia during dormant months.


    Once its roots are established, Alocasia reversa is a fast grower during warm months. They will fill out horizontally, but will rarely exceed 19 inches in height when grown indoors. These plants are perfect for areas with limited space & indirect light.



    ☠︎ TOXIC TO PETS ☠︎

  • Tips & Tricks

    ・Rotate your pot a quarter turn every time you water to ensure the plant receives even sunlight. This will prevent it from growing towards the light & becoming top heavy.

    ・Alocasia reversa loves to be a bit root bound, so there isn't an urgent need to repot them. However, these plants will outgrow their pots quickly as they are fast growers. When it is time to repot your reversa, select a pot that is 1-2" larger than the current pot. 

    ▹▹ You can also carefully divide your plant's root ball & repot into multiple containers. Separate the roots to divide. Routinely dividing the plant can help keep it a more manageable size if space is limited.

    ・Alocasias have a rhizome-type root system. these thick roots will store extra water for the plant. The nodes are located on the roots; therefore, to propagate Alocasia reversa, remove a section of the root & plant it in the soil. A new plant will sprout from the rhizome with enough time & the right conditions. 

    ・Watch out for pests! See our "Potential Problems" information section for more details on how to prevent scale, mealy bugs, & spider mites.

  • Potential Problems & How to Solve Them

    Mealybugs, scale, aphids, & spider mites are all common pests for Alocasias. 

    ▹  Inspect your plant often & treat as soon as you see them.
    ▹  Keep leaves clean & dust-free by wiping them down regularly
    ▹  If plant has an infestation, spray with insecticidal soap or neem oil to kill adult pests & their eggs.

    Crown, stem, & root rot is due to a fungus in the soil, often caused by wet conditions & heavy soil. This will have negative effects on the plant, causing damage to the crown, stem, &/or roots.

    Common Signs
    ・While the rot will eventually engulf the entire plant, most times the first sign of problems will happen at the soil line or on one side of the plant.
    ・Your plant may become stunted, failing to produce any new leaves.
    If the plant is rotting, there may be a foul odor, mushy stems, & droopy leaves. 
    ・How do you check?
    ▹ Gently pull on the seemingly affected stem; if it is sturdy & will not wiggle in the soil, it is probably not rotten. However, if the stem feels week & wiggles easily, it's most likely there is rot somewhere in the stem. 

    Unfortunately, rot usually goes undetected until it is fairly advanced. 
    { 1 } Remove the plant from the infected soil & repot in fresh, new soil.
    { 2 } Apply a fungicide. Drench soil with treatment for a minimum of two times per 30 days.
    { 3 }Trim back the affected foliage, leaving only the leaves that are healthy.
    { 4 } Repeat this process until only healthy foliage remains.


    A light gray or white powdery substance found on the plant's leaves.
    Unfortunately, powdery mildew is commonly found on Alocasias. 
    This fungus thrives in warm, dry climates, however, it will also form in areas that do not receive enough aeration. 

    Common Signs
    This problem is pretty obvious. Not only is it easy to see, it is also relatively easy to diagnose as there aren't many other conditions that resemble it . You'll know your plant is being affected by mildew if you see powdery white patches on your plant's leaves & stems.

    ・Make sure your plants are adequately spaced. If your plants are too close together airflow can become constricted, which will lead to powdery mildew.
    ・Make sure your plant is receiving enough light. If your Alocasia is in low light for a prelonged amount of time, especially after watering, the soil may have a hard time drying. This will eventually lead to growing fungus.
    ・Remove dead or diseased foliage with sharp shears or pruners.
    ▹ Make sure you disinfect your tool after each use - this fungus could spread to the next plant your tools touch!
    ・Purchase & use an organic fungicide with sulfer as the main ingredient. Use this treatment by coating all infected areas at least once per week for ~1 month.


    Leaf spot is caused by a fungus that grows on the leaves of your plants, causing them to turn brown & splotchy. As the disease progresses, the circle will grow in size, eventually causing your plant to lose leaves & show signs of overall ill health.

    Common Signs
    Small brown spots will begin to appear on the leaves of your plant, eventually spreading out.
    ▹ These splotches will cause the leaves to die & fall off.
    Your plant may look wilted & stunted

    ・ISOLATE the infected plant immediately! This fungus can spread & will infect your other plants if you aren't careful. 
    ・Make an organic treatment or buy an over-the-counter treatment.
    ▹ This concoction must contain sulfer & copper octanoate.
    ・Mix 1/2 teaspoon of baking soda per 1 gallon of water. Use the solution to wipe your leaves & spray the stems. 

    An infection caused by bacteria that leads to necrosis, causing small brown spots between the leaf veins, as well as crumpled & wilted leaves on your plant.

    Common Signs
    ・Small brown spots along the veins of your plant's leaves, which ultimately cause them to curl up & die. 
    ・Lesions on the fruit, stems, & roots are evident.
    ・In some cases, the spots are so large & raised that they cannot be missed.

    ⚠︎  There is no treatment for this disease!
    ・Quarantine your plant.
    ・Cut off all dead or dying leaves.
    ・ Try to stop the spread by using hydrogen peroxide as a disinfection treatment.
    ・Try to stop the spread by incorporating biological antagonists in the soil to help good bacteria fight off bad bacteria.



    Small yellow or brown insects that can destroy a houseplant in a matter of days.

    Common Signs
    ・If you look very closely you may be able to see the mites, however they are incredibly small.
    ・Look for powdery white webs that cover all the leaves of the affected plant.
    ・Sometimes mites will cause leaves to become discolored as they break out with thousands of tiny dots.

    Spray the plant with high pressured water from the hose. These insects do not like water & will often be defeated quite easily with this simple method. However, sometimes this isn't enough, especially for a large infestation.
    Insecticidal oils & soap prevent & kill existing spider mites.


    Soft-bodied, wingless, white & cottony insects found on the leaves & stems of  plants. They feed on the sap of the plant's leaves & stems. 

    Common Signs
    ・White clumps at leaf nodes, on the underside of leaves, along the stem, & especially in the nook where leaf meets stem. 
    ・You will find more mealy bugs on new growth (new leaves, new stems, etc.) than you will on any other part of the plant. 
    ・These bugs leave a waxy film on the plant.

    ・Easy to wash off with high pressure water from the hose. This is a great first line of treatment.
    ・Use your fingers & pluck them off/kill them manually.
    ・Wipe the leaves with a solution of (at most) 70% isopropyl alcohol & 30% water.
    ・Use insecticidal soap or neem oil.


    There are many types of scale. Each type comes in a different color, shape, & size, however, the most common type is a small, brown, & rounded lump found on your plant's leaves & stems. It comes in a soft & hard scaled variety.

    Common Signs
    ・Small round lumps inside the leaf.
    ・Small, brown, & rounded lumps on the plant's leaves & stems.
    ・Secretions, which lead to sooty mold.
    ・Yellow, wilted, &/or weathered leaves & plant.

    ・Dip a toothbrush in rubbing alcohol.
    ・Rinse your plant in the sink or shower to wash away any bugs you've missed.
    ・Following a trim of all of the dead & damaged foliage, use an organic or chemical pesticide.
    ・Use diluted neem oil weekly until plant returns to good health.
