Philodendron × mandaianum 'Ruby' – Hybrid Climber with Dark Red Foliage

Philodendron × mandaianum 'Ruby' is a 2014 hybrid between Philodendron erubescens and Philodendron hastatum. This cultivar sets itself apart with striking, dark red stems and petioles, paired with foliage that carries deep red tones seldom seen in climbing philodendrons. Beyond its colour, it is also a robust, forgiving hybrid that adapts easily to a range of indoor conditions.

What makes 'Ruby' distinctive

• Hybrid parentage: a cross of P. erubescens × P. hastatum, stabilised in 2014.
• Foliage colour: dark red to burgundy shades overlaying the leaf blades.
• Stem character: petioles and climbing stems flushed in ruby red.
• Growth habit: vigorous climbing vine, well suited to poles or trellises.

Background and breeding

The hybrid was originally produced in 2014 and has since become known among collectors as an accessible but visually distinctive philodendron. 'Ruby' builds on the climbing vigor of P. erubescens while integrating the cool-toned strength of P. hastatum, resulting in a compact but colourful foliage plant.

Care guidelines for Philodendron × mandaianum 'Ruby'

• Light: bright, indirect light brings out the deepest red tones; avoid direct midday sun.
• Temperature: performs best at 20 – 28 °C; keep above 16 °C for consistent growth.
• Humidity: 60 – 80% promotes lush foliage and healthy climbing shoots.
• Watering: water when the upper 2 – 3 cm of substrate dry slightly; do not leave roots waterlogged.
• Substrate: chunky, airy mix with bark, coco coir, and perlite for drainage and aeration.
• Feeding: light, regular fertilizer during active growth supports strong colour and leaf size.
• Support: a moss pole or totem helps leaves enlarge and stems remain upright.
• Alternative culture: adapts to mineral or semi-hydro substrates with stable moisture levels.

Challenges growers may encounter

• Pale leaves: often the result of low feeding; increase light fertilization.
• Leggy stems: indicates insufficient light; move closer to bright filtered exposure.
• Yellowing foliage: usually caused by excess watering or poorly draining substrate.
• Pest sensitivity: watch for thrips and spider mites; early inspection is key.

Collector’s perspective

• Rarity: less common than mainstream red philodendrons, offering a fresh colour profile.
• Display: foliage colour intensifies when grown against light-coloured or textured backgrounds.
• Adaptability: easier to care for than many red-foliaged hybrids, suitable for both novices and collectors.
• Safety: philodendrons are toxic if ingested; keep out of reach of pets and children.

Etymology

Genus:Philodendron (Schott, 1830), from Greek philo- “loving” + dendron “tree,” referencing its climbing habit.Hybrid name:× mandaianum marks the artificial cross; 'Ruby' is the cultivar selected for its dark red colouration.

Propagation and growth potential

• Cuttings: stem cuttings with 1 – 2 nodes root readily in warm, humid conditions.
• Medium: sphagnum moss or an airy aroid substrate ensures quick root development.
• Indoor size: typically 80 – 150 cm when supported; leaves enlarge with age and pole growth.
