Philodendron 'Painted Lady'

Philodendron 'Painted Lady' is a climbing variegated Philodendron with bright juvenile colour, red-toned stems and a steady upward habit. New leaves usually open in yellow-green to lime shades with darker green flecking, then deepen as they mature while keeping a mottled two-green pattern. The contrast between the warm petioles and fresh leaf colour is especially clear on fresh growth before the leaves settle into deeper green tones.

This cultivar benefits from support as the stem lengthens. Aerial roots form at the nodes, and the leaves sit more neatly when the plant is trained on a moss pole, plank or trellis. In a pot without support, older stems may lean or trail, but the natural growth direction is upward.

Mottled new growth and red petioles

• Stem habit: A lengthening climbing stem with visible nodes and aerial roots.
• Leaf colour: Yellow-green new growth marked with darker green mottling.
• Petioles: Pink to red stems and leaf stalks that stay visually important even as older leaves darken.
• Training: A support helps the plant hold larger, better-spaced leaves indoors.

McColley breeding background and mature plant shape

Philodendron 'Painted Lady' comes from Robert H. McColley’s Orlando, Florida breeding work. Its breeding background is recorded in USPP3958, published on 19 October 1976, with the cross Philodendron 'Burgundy' × Philodendron 'Emerald Queen'. The patent describes yellow-green mottled new leaves, mature two-green foliage, bright red stems and petioles, climbing growth and a need for staking as the plant develops.

The cultivar brings together red stem colour, climbing behaviour and mottled green-yellow foliage. The colour balance can vary between plants and between leaves on the same stem, so a healthy specimen may show brighter juvenile growth followed by calmer mature leaves.

The climbing habit matters for indoor care. Leaves are held on petioles from a central stem, and each node can produce aerial roots when humidity, contact and support are available. Support gives the stem a clear direction and helps new leaves expand without the plant becoming stretched or unstable in the pot.

Care for supported Painted Lady growth

• Light: Give bright, indirect light with protection from harsh midday sun. Pale leaf tissue can scorch quickly, while very dim conditions usually lead to smaller leaves and longer internodes.
• Watering: Water thoroughly once the upper part of the substrate has dried. The roots need moisture followed by oxygen, so the pot should never stay constantly wet.
• Substrate: Use an airy aroid mix with bark, coarse fibre, perlite or pumice and a moisture-retentive base. Dense potting soil can hold too much water around the roots.
• Humidity: Average indoor humidity is usually tolerated, but steadier humidity helps new leaves unfurl cleanly. A humidifier, grouped plants or a vitrine can help in very dry conditions.
• Temperature: Keep warm, ideally around 18–27°C. Cold, wet substrate is the main risk during cooler months.
• Feeding: Feed lightly during active growth with a balanced fertiliser. Pale new leaves are normal for this cultivar, so do not treat every yellow-green leaf as a deficiency.
• Pruning and support: Add a pole early if you want a vertical plant. Prune stretched stems above a node to shorten the vine and root cuttings when the plant is actively growing.

Problems to check on Philodendron 'Painted Lady'

• Soft yellowing leaves: Check root moisture first. A heavy substrate, oversized pot or frequent watering can reduce oxygen around the roots.
• Crisp pale patches: Move the plant away from direct sun or intense grow lights. Pale tissue marks more quickly than darker green tissue.
• Small leaves and long gaps between nodes: Increase light gradually and give the stem support so the plant can climb instead of stretching sideways.
• Stuck new leaves: Check humidity and airflow. Consistently dry air can make the cataphyll cling around new growth.
• Distorted fresh growth: Inspect petioles, cataphylls and leaf backs for thrips, spider mites, mealybugs or scale.

Handling and pet safety

Philodendron 'Painted Lady' should be kept away from pets and small children. Like other Philodendron, it contains calcium oxalate crystals that can irritate the mouth, throat and digestive tract if chewed or swallowed. Sap may also irritate sensitive skin, so wash your hands after pruning or taking cuttings.

Name and McColley cultivar context

Philodendron belongs to the Araceae family. The genus name comes from Greek roots meaning “loving trees”, a reference to the climbing habit seen in many species. The cultivar name 'Painted Lady' refers to the mottled, brushed-looking colour pattern across the leaves.

Philodendron 'Painted Lady' combines red petioles, mottled yellow-green new growth and a documented McColley hybrid background.
