(Shipped in its own box) Alocasia Regal Shield - The Majestic Statement Plant

Introducing the Alocasia Regal Shield, one of the most spectacular and sought-after Alocasia hybrids available! This stunning plant truly lives up to its regal name, featuring enormous shield-shaped leaves in deep, dark green that borders on black, contrasted beautifully by rich burgundy-purple undersides and bold light green veining. It's a plant that commands attention and transforms any space into a tropical sanctuary.

This impressive hybrid was created in 2007 by renowned hybridiser LariAnn Garner at Aroidia Research in Florida, crossing Alocasia odora with Alocasia reginula 'Black Velvet'. The result is a plant that combines the impressive size and vigour of A. odora with the velvety dark leaf texture of Black Velvet. The cross was considered unlikely due to the vastly different characteristics of the parent plants, making this hybrid a true achievement in Alocasia breeding. It was granted US Plant Patent PP27,050 in 2016 and has since become one of the most prolific Alocasia hybrids in cultivation worldwide.

• Award-Winning Hybrid! Patented cultivar bred for impressive form and indoor performance.
• Surprisingly Adaptable! More tolerant than many Alocasias once established.

The Dramatic Look

What makes Alocasia Regal Shield so captivating is its incredible colour contrast. The upper leaf surface displays a deep, dark green that can appear almost black in certain lighting, with a matte, velvety sheen that's remarkably eye-catching. This dark canvas is beautifully accented by prominent light green to creamy white veins that create a striking visual pattern.

Turn the leaf over and you're greeted by an equally stunning burgundy-purple to deep red underside, adding unexpected colour and depth to the plant's appearance. The thick, light green stems (petioles) provide additional contrast, holding the substantial leaves proudly upright in an architectural display.

Mature specimens can produce fragrant lily-like flowers in spring and summer, with a light green spike surrounded by a creamy spathe. The blooms emit a beautiful perfume that's particularly noticeable at night.

Light Requirements

Alocasia Regal Shield thrives in bright indirect light but is adaptable to medium light conditions. A position near an east or west-facing window where light is filtered through a sheer curtain works beautifully. The plant can handle some morning sun but avoid harsh afternoon direct sunlight, which will scorch the leaves.

Too little light will slow growth, reduce leaf size, and can trigger dormancy. If your plant starts dropping leaves or producing smaller foliage, it may need a brighter position. Rotate your plant every few weeks to ensure even growth on all sides, as it will naturally lean towards the light source.

Watering Your Alocasia Regal Shield

Consistent moisture is key to keeping your Regal Shield happy, but there's a fine line between moist and waterlogged. Allow the top 5cm of soil to dry out between waterings, then water thoroughly until it drains from the bottom of the pot. Never let the plant sit in standing water.

It's important to only water when it suits the environment your plant is living in, as everyone's home is different!

During the warmer growing months (spring through summer), you'll water more frequently, perhaps every 7-10 days depending on conditions. In winter, when growth slows, reduce watering and allow the soil to dry out more between drinks. Overwatering is the most common cause of problems with Alocasias, leading to root rot and fungal issues.

Regal Shield can be sensitive to minerals and chemicals in tap water, which may cause leaf spotting. If possible, use filtered water or rainwater, or leave tap water out overnight before using to allow chlorine to dissipate.

The Perfect Potting Mix

This Alocasia needs a rich, well-draining potting mix that holds moisture without becoming waterlogged. Our Ultimate Aroid Mix is ideal, or create your own using a combination of quality potting mix, orchid bark, perlite, and coco coir. The soil should be slightly acidic to neutral (pH 5.5-7.0) and provide excellent aeration to the roots.

Good drainage is essential. Always use a pot with drainage holes and avoid letting the roots sit in soggy soil, which quickly leads to root rot. When repotting, choose a container only slightly larger than the current one, as Alocasias prefer to be somewhat snug in their pots.

Humidity Matters

Coming from tropical parentage, Alocasia Regal Shield loves humidity levels between 60-80%. In the average Australian home, particularly during winter when heating dries the air, you'll likely need to boost humidity around your plant.

The best way to increase humidity is by grouping your Regal Shield with other tropical plants to create a humid microclimate. Bathrooms and kitchens with good natural light often provide the extra humidity these plants crave. A humidifier is an excellent investment if you're serious about growing humidity-loving tropicals.

Signs of low humidity include brown, crispy leaf edges and tips. If you notice this, focus on increasing the ambient moisture around your plant.

Temperature

Alocasia Regal Shield prefers warm, stable temperatures between 18-27°C. It doesn't tolerate cold well, so keep it above 15°C and well away from cold drafts, air conditioning vents, and draughty windows. Prolonged exposure to temperatures below 15°C can trigger dormancy and leaf drop.

Despite being cold-sensitive, Regal Shield is actually quite wind resistant and can be grown outdoors on sheltered balconies or patios during the warmer months, as long as it's protected from direct sun and brought inside when temperatures drop.

Feeding for Healthy Growth

Alocasia Regal Shield is a strong feeder that benefits from regular nutrition during the growing season. From September through March, feed with Growth Technology Foliage Focus at 3-5ml per litre of water at every watering for optimum results. Add Growth Technology Rootzone at 1ml per litre every 2-4 weeks in conjunction with your regular feeding to support the substantial root system.

Flush monthly with plain water to remove traces of mineral salts build up, which can cause leaf tip burn. Reduce feeding in autumn and stop completely during winter when growth slows or the plant goes dormant.

Winter Dormancy

Like many Alocasias, Regal Shield may enter a dormancy period during the cooler, darker months. Growth will slow dramatically, and the plant may drop some or all of its leaves. This is a natural response to reduced light and cooler temperatures, not a sign of plant death!

During dormancy, reduce watering significantly (the underground rhizome is still alive and can rot if kept too wet), stop fertilising, and keep the plant in a warm spot. Avoid the temptation to overwater or fuss too much. Once spring arrives and conditions improve, new growth will emerge from the rhizome.

You can help prevent dormancy by providing supplemental light and maintaining warmth and humidity through winter.

Propagation

Alocasia Regal Shield produces corms (underground bulb-like structures) and offsets that can be separated and propagated. When repotting, check for small cormels or baby plants growing from the mother plant. These can be carefully separated and potted up individually.

Interestingly, Regal Shield is believed to be sterile and does not produce viable seeds, which is common in hybrid plants with mismatched chromosome counts from different parent species. This means propagation is limited to division and corm separation. Use Clonex Clone Solution to help divisions establish strong root systems.

Growing Support

Alocasia Regal Shield has a naturally upright growth habit and typically doesn't require staking. The thick stems hold the large leaves proudly erect. However, if your plant becomes top-heavy or develops a lean towards the light, you can provide support with a simple stake or use one of our Grow Vertical Propsticks for a more elegant solution.

Care Tips for Success

• Prioritise humidity by grouping with other plants or using a humidifier.
• Avoid overwatering! Let the top 5cm dry between waterings.
• Use well-draining soil to prevent root rot.
• Keep warm and away from cold drafts and temperature fluctuations.
• Rotate regularly for even growth.
• Wipe leaves regularly to remove dust and maintain their beautiful sheen.
• Don't panic at dormancy! Leaf drop in winter is normal.
• Use filtered or rainwater if possible to prevent leaf spotting.

Common Issues and Solutions

Yellow leaves: Most commonly caused by overwatering or insufficient light. Check your watering schedule and ensure soil is drying adequately. Can also indicate natural ageing of older leaves.

Brown, crispy leaf edges: Usually a sign of low humidity or salt buildup from tap water. Increase ambient moisture and flush soil regularly.

Drooping leaves: Can indicate either overwatering (check for mushy stems and root rot) or underwatering (soil bone dry). Also caused by cold stress or sudden temperature changes.

Leaf drop: Normal during winter dormancy. At other times, may indicate cold stress, insufficient light, or inconsistent watering.

Pale or faded leaves: Too much direct sunlight bleaching the foliage. Move to a spot with bright but indirect light.

Spider mites: Regal Shield has moderate resistance to spider mites but can still be affected, especially in dry conditions. Check undersides of leaves regularly and treat with insecticidal soap or neem oil if needed.

Important Safety Note

Alocasia Regal Shield contains calcium oxalate crystals which are toxic if ingested by pets or humans. Ingestion can cause mouth and throat irritation, difficulty swallowing, and stomach upset. Keep this plant out of reach of curious pets and children.
