Alocasia Velvet Dragon: Wim Philtjens' Second Hybrid and the Legacy of Alocasia tandurusa 'Jacklyn'

When a hybridiser creates one plant that captures the serious attention of the collector world, that is notable. When their second hybrid, announced shortly after the first, demonstrates an equally clear aesthetic vision and equally interesting parentage, it signals that something genuinely significant is happening. Alocasia Velvet Dragon is Wim Philtjens' second documented hybrid creation, following Alocasia Blood Bone, and it demonstrates that Philtjens' hybridisation work is not a one-off experiment but a considered, ongoing programme with a clear vision.

Where Blood Bone crosses Alocasia cuprea with Alocasia micholitziana 'Green Velvet' to produce its distinctive red-stemmed character, Velvet Dragon takes Alocasia micholitziana 'Green Velvet' in a completely different direction, crossing it with Alocasia tandurusa 'Jacklyn', the deeply lobed, antler-like Sulawesian species that became one of the most coveted Alocasia of the Covid-era plant collecting boom. The result is a hybrid that combines the velvety, dark-leaved character of 'Green Velvet' with the dramatic structural character of Jacklyn, creating a plant with features that neither parent could provide alone.

This guide explores both parent species in depth, explains what each contributes to Velvet Dragon, and provides comprehensive growing guidance for collectors who have acquired this exceptional hybrid.

The Parents: Two Exceptional Species Combined

Alocasia micholitziana 'Green Velvet': The Recurring Philtjens Parent

Alocasia micholitziana 'Green Velvet', native to the Philippines, characterised by its velvety dark green arrow-shaped leaves with prominent white venation, and correctly named as detailed in our Blood Bone guide, is clearly a plant that Wim Philtjens values highly as a hybridisation parent. Its appearance in both Blood Bone (as pollen parent) and Velvet Dragon (as berry carrier, or in some documented accounts as pollen parent) reflects the characteristics it contributes: the velvety foliage texture, the rich dark green colouration, the moderate humidity tolerance that makes hybrids involving it more practical for indoor collection, and the established popularity with collectors that gives its hybrid offspring an immediate audience.

The 'Green Velvet' parent also contributes to the family identity of the Philtjens hybrids. Serious collectors who come to know Blood Bone and Velvet Dragon quickly recognise common characteristics that trace back to 'Green Velvet', a thread of botanical inheritance that is visible to those who know what to look for.

Alocasia tandurusa 'Jacklyn': From Sulawesian Rainforest to Collector's Hybrid Parent

Alocasia tandurusa is formally described by Prameswara and Hay (2023), making it one of the more recently scientifically documented Alocasia species in spite of having been in horticulture under the cultivar name 'Jacklyn' since well before formal description. The story of how it entered cultivation is itself significant for understanding the plant's collector status.

A local resident of Gorontalo in Northern Sulawesi named Enjie Jacklin purchased the first few individuals of the species and popularised it online under the name Alocasia 'Jacklin', which has since been misspelt as 'Jacklyn' in widespread commercial use. Indonesian growers, feeling that the original Jacklin's credit should be properly acknowledged while also working toward a more standardised nomenclature, have since promoted the botanical name Alocasia tandurusa. The specific epithet is an attempt at latinisation of the Indonesian name 'Tanduk Rusa', meaning deer antlers, referring to the deeply lobed, antler-like leaf blades.

Aroidpedia's entry on Alocasia tandurusa contains a note that is worth highlighting for any collector interested in the ethics as well as the botany of rare plant collecting: "Since the plant came to be known to horticultural collectors worldwide during the aroid-mania of the Covid pandemic, we understand that what is thought to be the main population has been severely depleted." This is an important reminder that demand from collector communities, however enthusiastic and well-intentioned, creates real-world pressures on wild plant populations that deserve serious consideration.

The plant itself is extraordinary. Native to the Bolaang Mongondow Regency of Sulawesi Utara in the Minahasa peninsula of Northern Sulawesi, it grows in constantly warm conditions (approximately 18–31°C) in humid forest understory between 500–1,000m altitude. Its deeply pinnatifid, antler-shaped blades display dark venation across a fine, slightly velvety surface, the pubescent leaf quality that partially echoes the micholitziana 'Green Velvet' parent in the Velvet Dragon cross. Thick, mottled petioles rise from a creeping rhizome. The deeply lobed blade structure is unlike virtually any other Alocasia in cultivation, giving plants a bold, sculptural appearance that photographs dramatically and impresses in person.

What Velvet Dragon Inherits

The combination of these two parents in Velvet Dragon creates a hybrid where the contributing characteristics of each parent are legible but have been reinterpreted through the lens of the cross. From micholitziana 'Green Velvet' comes the dark, rich leaf colouration, the velvety surface quality (somewhat modified in the hybrid), and the upright growth character. From tandurusa 'Jacklyn' comes influence on the leaf form, the hybrid shows a degree of the structural complexity and lobed character of Jacklyn, though in a form that is less dramatically dissected than pure tandurusa and more integrated with the 'Green Velvet' leaf shape.

The result is a plant with an aesthetic that occupies a compelling middle ground: more structurally interesting and complex than standard micholitziana 'Green Velvet', more indoor-manageable and growth-consistent than pure tandurusa, and with a surface quality and leaf character that is genuinely its own rather than simply an average of its parents. This is what successful hybridisation achieves, not merely a mid-point between two species but a new plant with its own identity and its own specific collector appeal.

Growing Alocasia Velvet Dragon

Velvet Dragon's growing requirements sit between those of its two parents, warmer and more humidity-demanding than micholitziana 'Green Velvet' alone, but without the very specific requirements that pure tandurusa demands at higher difficulty levels.

Light

Bright indirect light is the fundamental requirement. Velvet Dragon's dark, velvety-influenced foliage benefits significantly from good light, the depth and richness of the dark green colouration is most apparent under bright conditions, and the surface quality most engaging under light that allows the texture to create subtle shadow play. Position within 1–1.5 metres of a well-lit window.

During UK autumn and winter, supplementation with LED grow lights is strongly recommended. The Jacklyn heritage makes Velvet Dragon somewhat more sensitive to low light than standard 'Green Velvet', its Sulawesian origins (consistently warm, tropical lowland-to-montane conditions) do not prepare it well for the dramatic light reduction of a UK winter. Maintaining 10–14 hours of supplemental light through the dark months keeps growth consistent and prevents the regression that low-light winter conditions can cause.

Avoid direct sun. The velvety, textured leaf surface of Velvet Dragon, like that of 'Green Velvet' itself, can heat up faster than glossy-leaved Alocasia under direct sun, and trichome-covered surfaces are more susceptible to bleaching and burning than smooth ones.

Temperature

Maintain 20–27°C during active growth. Velvet Dragon prefers slightly warmer conditions than some hybrid Alocasia, reflecting the tandurusa parent's lowland-to-lower-montane Sulawesian habitat where temperatures remain consistently warm. The critical threshold is 16°C, below this, growth pauses and the plant becomes vulnerable. UK rooms that cool significantly at night, particularly near single-glazed windows in winter, should be monitored carefully.

Humidity

Target 65–80% ambient humidity. The tandurusa 'Jacklyn' parent's forest understory origins, high humidity, consistent warmth, filtered light, inform Velvet Dragon's humidity requirements more than the micholitziana 'Green Velvet' parentage does. In the absence of adequate humidity, the leaf quality deteriorates: the rich dark colouration becomes less vivid, the surface texture appears less refined, and margin browning develops. A quality humidifier is strongly recommended rather than relying on passive humidity management.

Avoid misting directly onto the leaves. The velvety-influenced surface texture of Velvet Dragon can trap moisture droplets in ways that glossy-leaved Alocasia cannot, creating conditions that favour fungal issues. Ambient humidification is always preferable to foliar misting for any plant with textured leaf surfaces.

Substrate and Watering

Well-draining chunky aroid mix, the standard recommendation for collector Alocasia and entirely appropriate for Velvet Dragon. Fluval Stratum for corm propagation. The micholitziana 'Green Velvet' parentage means Velvet Dragon is somewhat more tolerant of consistent moisture than pure cuprea-influenced hybrids, it prefers the substrate to be consistently moist (though never waterlogged) rather than drying significantly between waterings.

Water when the top 2–3cm is dry, watering thoroughly. In summer under good light, this may mean watering every 4–6 days; in winter under reduced light and slower growth, reduce to once every 10–14 days or less. Complete drainage is essential at all times, Velvet Dragon in standing water develops root rot faster than growers typically expect. Our guide to Alocasia root rot provides full guidance for identification and recovery.

Feeding

Half-strength balanced fertiliser every second or third watering during active growth (broadly late spring through early autumn). Stop entirely through winter. The Philtjens hybrids, Blood Bone and Velvet Dragon, are both plants where conservative feeding at half-strength consistently outperforms aggressive full-strength applications. The hybrid genetics create sensitivity to excess nutrition that pure species plants may not share to the same degree. Our plant feed collection covers appropriate products for collector-grade Alocasia.

Propagation and Corm Development

Like other Alocasia, Velvet Dragon produces corms, swollen underground storage structures that can be removed and propagated separately. Our guide to Alocasia corm propagation covers this process in detail. Velvet Dragon corms are particularly valuable given the plant's rarity, each corm represents a potential new specimen of this documented Philtjens hybrid. Fluval Stratum is our recommended propagation substrate, with the corm positioned just at the substrate surface and maintained in warm, humid conditions until sprouts emerge.

Velvet Dragon Within the Philtjens Hybrid Collection

For collectors who have built or are building a collection specifically around Wim Philtjens' documented hybrids, Velvet Dragon and Blood Bone form the current core of a thematically coherent group, two plants from the same breeder's deliberate programme, each demonstrating a different vision of what Alocasia micholitziana 'Green Velvet' can become when crossed thoughtfully with an exceptional second species.

Alongside Golden Bone, the natural/presumed-natural hybrid involving the same two parent species as Blood Bone in reversed crossing order, these three plants constitute one of the most botanically coherent and collector-relevant groupings in the contemporary Alocasia world. Each tells a different story about hybridisation and inheritance; together they tell a story about a specific family of plants that is more interesting than any individual specimen alone.
