Anoectochilus roxburghii × Ludisia discolor ‘Spiderman’

A trade-named jewel orchid linked to Ludochilus Dominyi

The stated parent formula Anoectochilus roxburghii × Ludisia discolor corresponds to the registered grex Ludochilus Dominyi, introduced by Veitch in 1865. Verified crosses between those same two species belong to that grex, including later remakes. ‘Spiderman’ is a later trade or cultivar label without a published individual history, so the label alone does not verify the parentage or identity of the clone in trade.

A. roxburghii is native from the Himalaya through southern China and Indo-China, while L. discolor ranges more widely through southern China and Southeast Asia. A cultivated hybrid between them has no wild population.

Caring for Anoectochilus roxburghii × Ludisia discolor ‘Spiderman’ indoors

Light

Anoectochilus roxburghii × Ludisia discolor ‘Spiderman’ needs soft, useful daylight near a north-east window or under a diffused grow light. Avoid direct afternoon rays and acclimate it even to mild morning sun. A dark position weakens the creeping shoots and gives small widely separated leaves; excess light fades the surface and crisps the edges. The pale markings are part of the plant’s inherited pattern. Healthy contrast comes from sound leaves, not deliberate sun stress.

Watering

Keep the root zone of Anoectochilus roxburghii × Ludisia discolor ‘Spiderman’ gently moist, never swampy. Water thoroughly at the first sign that the surface is drying and remove runoff. Waiting until the leaves droop risks loss of fine roots, but watering already-wet mix can damage the stem base. Judge moisture below the moss or top dressing rather than touching only the surface. Light, warmth, airflow and root occupancy determine how quickly the next watering is needed.

Substrate and roots

Anoectochilus roxburghii × Ludisia discolor ‘Spiderman’ grows through the surface of a soft, springy terrestrial mix. Combine fine bark and chopped sphagnum with coir or a little quality potting substrate and pumice. The shallow roots need close contact without compression. Coarse orchid mix dries unevenly, while old moss can exclude air. Set the stem at its former level in a small draining pot and use low-mineral water to limit salt deposits.

Temperature

Anoectochilus roxburghii × Ludisia discolor ‘Spiderman’ is comfortable at 19–27 °C and needs protection below roughly 16 °C. Cool wet conditions cause a rapid root setback. Place the plant away from winter glass, air-conditioning outlets and exterior-door currents. Avoid direct heating, which can desiccate one side of the creeping plant. Keep temperatures even while a new leaf is opening, since soft tissue responds poorly to a sudden cold night.

Humidity and airflow

Provide Anoectochilus roxburghii × Ludisia discolor ‘Spiderman’ with moderately high humidity, ideally 65–80%. Average dry indoor air can be tolerated for a time, but the growing tip and soft leaf edges may deteriorate. Humidity must come with gentle ventilation around the stem and damp mix. Do not use routine misting as the main method; it briefly wets the surface and may mark pale veins. A ventilated enclosure creates more stable conditions.

Fertilising

Anoectochilus roxburghii × Ludisia discolor ‘Spiderman’ requires dilute, balanced nutrition. Apply a complete orchid or foliage feed at one-eighth to one-quarter strength every four to six weeks when new tissue is visible. Reduce further in fresh mix or moderate light. A plant still growing in winter can be fed lightly. Avoid strong solutions and dry-root feeding, then rinse with low-mineral water often enough that soluble salts do not collect.

Repotting

Anoectochilus roxburghii × Ludisia discolor ‘Spiderman’ is ready for repotting when its root mat reaches the pot wall, the substrate collapses or the stem begins circling the rim. Use a shallow container one small size larger. Lift the plant and its attached mix together because bare-rooting damages the delicate roots. Work in warm active conditions, keep the creeping stem unburied and separate only a section that already supports roots and a live growing point.

Support, pruning, handling and leaf care

Anoectochilus roxburghii × Ludisia discolor ‘Spiderman’ may make a sturdier creeping stem than some small Anoectochilus, but it should still be guided across the surface rather than trained upright. This terrestrial orchid should travel across the pot surface without a trellis. Redirect only young flexible growth, and divide after the new position has rooted. Snip dead leaves cleanly. Do not wipe the velvet blade; use a low-pressure blower, brush or brief gentle rinse instead.

The red web, creeping stems and unhealthy nodes

• Dark velvet leaves carry a red or copper web: The vivid web-like venation is characteristic of plants sold under this Anoectochilus × Ludisia formula. Colour can vary between leaves without signalling a deficiency.
• Stems creep, branch and become less rosette-like: Some Ludisia-like branching is normal in plants sold under this intergeneric formula. Let firm stems run across the surface or pin them loosely for rooting rather than burying the fleshy nodes.
• A tall flower spike forms and foliage growth pauses: Flowering is normal and the traded plant may bloom freely. Remove the spike after it finishes if desired, then resume ordinary light feeding only when new vegetative growth is active.
• A node turns soft where it touches wet medium: Lift sound stems away from the affected area, cut out the rot and improve drainage and air exchange. A firm tip can be rooted separately as insurance.
• Red veins are joined by fine pale stippling or webbing: Those new marks indicate spider mites, not extra pattern. Isolate the plant and clean and treat every branch because mites can move through the low, spreading canopy.

Pet Safety

The effects of eating the hybrid Anoectochilus roxburghii × Ludisia discolor ‘Spiderman’ have not been established in cats or dogs. Until the hybrid itself is better understood, keep it away from pets that chew plants. Contact a veterinarian after substantial ingestion or if vomiting, diarrhoea, drooling or unusual behaviour develops.

Ludochilus Dominyi and ‘Spiderman’

Ludochilus is the hybrid genus used for crosses between Ludisia and Anoectochilus. The grex Dominyi was registered by Veitch in 1865 for A. roxburghii × L. discolor and applies to verified offspring of that parent formula, including later remakes. ‘Spiderman’ refers to the web-like leaf veins, but no published record establishes its selector, individual parent plants or clonal history.
