Alocasia 'Stingray', the alocasia with tapered leaves

A cultivar derived from Alocasia macrorrhizos (Alocasia macrorrhizos), Alocasia 'Stingray' looks more like a fish than elephant ears. This is due to its slender, ray-like leaves.

How to recognize Alocasia 'Stingray'?

Alocasia 'Stingray' is an upright perennial. Larger than alocasia 'Frydek Variegata, it reaches a height of two meters with the same spread.

The plant is almost acaule. Only the long, upright, zebra-shaped petioles are visible.

The glossy, medium-green leaves are wavy. Raised veins stand out on the upper surface of the leaf blade. Round, the leaves end in a fine, highly curved point, similar to the tip of a ray. It's this feature that gives the variety its name ( stingray ).

Flowering, rare indoors, seems insignificant compared to the decorative foliage. The flower is typical of the Araceae family. It consists of a spadix surrounded by a spathe.

Alocasia 'Stingray' is a poisonous plant. Its leaves, roots and stems contain calcium oxalate crystals. This substance causes digestive problems, skin irritation and inflammation of the mucous membranes. Keep your specimen out of reach of small children and pets. And remember to wear gloves when handling it.

Our maintenance tips

Alocasia 'Stingray are not plants to be placed in everyone's hands. They need light, rich soil, a little knowledge and a lot of attention.

WateringWatering

Alocasia 'Stingray appreciate freshness. Their soil must be kept slightly moist in spring and summer. But the plant doesn't like excess. Be careful not to soak the substrate!

Provide water at room temperature, without lime. You can, for example, collect rainwater or use filtered water.

Once you've watered your Alocasia macrorrhizos 'Stingray', empty any stagnant water from the saucer or planter. It may rot the roots.

SpraySpray

Your Alocasia 'Stingray is a tropical plant. It appreciates humidity. Spray its foliage with water at room temperature.

Avoid calcareous water, which leaves white marks on the leaves. Prefer rainwater or filtered water.

RepottingRepotting

Every spring, repot your Alocasia macrorrhizos 'Stingray' to give it more space.
Repotting is a delicate operation. Take care not to damage the roots in the process.

Choose a pierced pot, preferably terracotta. This material distributes humidity and protects the roots. The pot should be larger than the root ball to give the root system room to develop.

Place a bed of clay balls or gravel and cover with a drainage filter. Fill the pot with potting soil for green plants. Add sand or perlite for drainage and compost for nutrients. Plant your Alocasia macrorrhizos 'Stingray' in the center and fill with substrate. The root ball should reach the surface. Tamp down and water for the first time to encourage rooting.

To improve humidity, place the plant on a saucer filled with moist clay balls.

FertilizationFertilization

To promote the growth of your Alocasia macrorrhizos 'Stingray', apply fertilizer in spring and summer.
Apply liquid green plant fertilizer diluted with water.

CleaningCleaning

Dust on leaves interferes with photosynthesis. To make sure your Alocasia 'Stingray gets all the available light, clean its foliage with a clean, damp cloth.

Caution! All parts of the plant are toxic. Wear gloves and wash your hands after touching the foliage.

PlantationPlantation

When the risk of frost has passed, it's time to plant.
Soak the rootball of your Alocasia 'Stingray. Meanwhile, choose a spot in partial shade. Dig a hole twice the size of the root ball.

Plant your Alocasia 'Stingray in the center. Don't bury it too deeply- the rootball should be flush with the surface.

Fill in with a mixture of garden soil and compost, then water. You can mulch the base with organic matter to protect the plant from the cold.

CuttingCutting

Cutting is carried out during the strong growth phase, generally in spring and early summer.
Take the shoots that form at the base of your Alocasia 'Stingray. The larger they are, the greater the chances of success. Choose shoots with several leaves.

Cut off the new plant and its roots with a clean, sharp blade.
Prepare buckets with potting soil similar to that used for adult plants. Translucent pots are best. You'll be able to monitor root growth.

Place the bulbils on the surface, flat side down and pointed side up. Water and then place your bulbils in a greenhouse or transparent crate.
