About

Imperial Red is a self-heading Philodendron cultivar grown for its new leaves, which emerge a deep burgundy-red before darkening to a glossy near-black green as they mature. Like its close relative Prince of Orange, it grows as a compact rosette from a single crown rather than climbing, making it a tidy, architectural houseplant. It is widely produced by tissue culture and sold at accessible prices across UK garden centres and online retailers, valued for its bold colour contrast and low maintenance requirements.

Before You Buy

Species-specific things to check when evaluating a listing

  • Look for a healthy central crown with no signs of rot at the base
  • New leaves should show a clear deep red flush, not plain green
  • Check for scale insects on petioles, a common issue on self-heading Philodendrons

Cultivar character is preserved through vegetative cuttings

Divide at the base once multiple crowns develop; single-node stem cuttings root readily in water or moist substrate.

Care Guide

Growing Conditions

Substrate

Well-draining mix: 50% potting compost, 30% perlite, 20% orchid bark.

Watering

Water when the top 3-4 cm of substrate is dry. Reduce frequency in winter.

Humidity

40-60% is tolerated well; higher humidity encourages larger, glossier leaves.

Fertilising

Balanced liquid fertiliser at half strength every 4 weeks in spring and summer.

Repotting

Every 12-18 months, or when the crown outgrows its pot.

Common Problems

Problem

New growth emerging green rather than red

Cause

Insufficient light

Fix

Move to brighter indirect light to intensify the red flush on new leaves

Problem

Yellow lower leaves

Cause

Overwatering or natural leaf drop with age

Fix

Check substrate moisture before watering; some lower-leaf loss is normal as the plant matures

The Other Colour-Change Cultivar

Imperial Red is often sold alongside Prince of Orange as the darker-toned counterpart, and the comparison is a fair one — same self-heading habit, same tissue-culture-driven affordability, same low-maintenance appeal. The difference is entirely in the new-growth colour: a deep wine-red here instead of copper-orange.
