Philodendron 'Black Cardinal'

Philodendron 'Black Cardinal' is a bold, self-heading hybrid prized for its deep burgundy to near-black foliage and strong, upright growth. New leaves emerge with a coppery-red tone before darkening to rich chocolate-maroon, creating a striking contrast between old and new growth. Its wide, paddle-shaped leaves have a soft satin sheen and grow in a neat, layered rosette that gives the plant a sculptural, architectural presence.

Unlike trailing philodendrons, ‘Black Cardinal’ stays compact and doesn’t climb—making it perfect for desktops, side tables or floor pots in bright indoor spaces. It's low-maintenance, visually dramatic, and ideal for adding dark contrast to lush plant collections.

Toxic if ingested.

Comprehensive Care Instructions for Philodendron 'Black Cardinal'

Lighting Requirements

Indoors: Prefers bright, indirect light to maintain its deep colour. Tolerates medium light but may grow slower and produce smaller leaves. Avoid direct sun, which can scorch or fade the foliage.
Outdoors (mild climates): Grow in filtered light or full shade. Protect from strong sun and cold.

Watering Regimen

Active Growth (Spring to Autumn):
Water when the top 2–4cm of soil is dry. Keep soil lightly moist but not soggy. Ensure pot has good drainage.
Cooler Months:
Allow soil to dry a little more between waterings. Reduce frequency to match slower growth.

Temperature & Humidity

Thrives in warm temperatures between 18°C–28°C. Avoid cold drafts or temperatures below 12°C.
Prefers moderate to high humidity but tolerates average indoor conditions well. Mist occasionally in dry spaces.

Fertilizing

Feed every 4–6 weeks in spring and summer with a balanced, diluted liquid fertiliser. Hold off feeding in winter unless under grow lights.

Pruning & Maintenance

Remove old or damaged leaves at the base to keep the plant tidy. Wipe leaves gently to remove dust and enhance their dark sheen.

Repotting

Repot every 1–2 years or when rootbound. Use a chunky, free-draining aroid mix with bark, perlite and compost.

Pests & Troubleshooting

Generally pest-resistant but may attract mealybugs or fungus gnats in very damp conditions.
Pale or faded leaves may indicate too much light. Yellowing may suggest overwatering.

Important Note: Dark, Moody & Low-Fuss

Philodendron 'Black Cardinal' is a standout choice for lovers of dark foliage. Its non-climbing habit and bold, sculptural form make it ideal for modern interiors and statement containers.
