Philodendron 'Red Sun' (Red Sun Philodendron)

Philodendron 'Red Sun', commonly known as Red Sun Philodendron, is a stunning tropical foliage plant admired for its vibrant colour-changing leaves and compact growth habit. New foliage emerges in brilliant shades of red, copper, orange, and burgundy before gradually maturing to deep green, creating a constantly evolving display of colour throughout the year.

This self-heading philodendron forms a dense, upright clump rather than producing long climbing or trailing stems. Its colourful foliage and manageable size make it a popular choice for homes, offices, retail spaces, and contemporary interior plant styling.

With its bold tropical appearance and relatively easy-care nature, Red Sun Philodendron is an excellent feature plant for both beginner and experienced plant enthusiasts.

Growth Habit and Size

Red Sun Philodendron grows as a compact, upright clumping plant with leaves emerging from a central crown.

Unlike climbing philodendrons, it remains self-supporting and develops into a dense, rounded specimen.

Indoors, mature plants typically reach between 60cm and 1 metre in height and spread, depending on growing conditions and container size.

Growth is moderate to fast during warmer months when provided with adequate light, warmth, and moisture.

Care Requirements

Light

Prefers bright, indirect light.

Bright conditions encourage the strongest foliage colour and healthiest growth.

Can tolerate medium light levels, although colour intensity may reduce.

Avoid prolonged direct sunlight, which can scorch leaves.

Watering

Allow the top few centimetres of soil to dry between watering.

Water thoroughly and allow excess moisture to drain freely.

Reduce watering frequency during cooler months when growth naturally slows.

Soil

Requires a rich, well-draining potting mix.

A premium indoor potting mix blended with perlite and orchid bark provides excellent drainage and aeration.

Temperature and Humidity

Thrives in temperatures between 18°C and 30°C.

Protect from temperatures below 12°C.

Prefers moderate to high humidity but adapts well to average indoor conditions.

Maintenance

Remove damaged or ageing leaves as required.

Wipe foliage occasionally to remove dust and maintain its appearance.

Apply a balanced liquid fertiliser monthly during spring and summer.

Repot every 2–3 years or when roots begin filling the container.

Rotate the plant periodically to encourage even growth.

Common Issues

Yellow Leaves

Usually caused by overwatering or poor drainage.

Brown Leaf Edges

Can occur due to underwatering, low humidity, or environmental stress.

Dull Foliage Colour

Often caused by insufficient light.

Slow Growth

May result from low temperatures, inadequate light, or nutrient deficiencies.

Root Rot

Most commonly associated with excessive watering and poorly draining soil.

Applications

Suitable for:

Indoor feature plants

Office environments

Reception areas

Apartment living

Retail displays

Commercial interiors

Tropical-themed interiors

Decorative containers

Its colourful foliage makes it an excellent focal point in both modern and traditional interiors.
