Ardisia Crenata 'Cool Fire'

Ardisia crenata 'Cool Fire', commonly known as Cool Fire Ardisia, is a rare ornamental shrub cultivar prized for its glossy foliage and clusters of bright red berries that persist through winter. Native to Asia, this evergreen species is often grown indoors or in shaded outdoor gardens for its striking year-round display.

Growth Requirements

Light

• Prefers bright, indirect light indoors or partial shade outdoors.
• Avoid harsh direct sun, which can scorch leaves.
• Too little light reduces berry production and leaf gloss.

Water

• Keep soil consistently moist, but not soggy.
• Allow the top layer to dry slightly before watering again.
• Sensitive to drought stress; leaves may wilt quickly if neglected.

Humidity

• Thrives in moderate to high humidity (50–70%).
• Benefits from humidifiers or pebble trays indoors.
• Dry air can cause leaf edges to brown.

Temperature

• Optimal range: 65–80°F.
• Protect from drafts and cold below 55°F.
• Stable warmth encourages berry set and foliage health.

Soil

• Use a well-draining, slightly acidic mix: peat moss, perlite, and loamy soil.
• Avoid alkaline soils, which can cause nutrient deficiencies.

Fertilizer

• Feed monthly during active growth with a balanced liquid fertilizer.
• Reduce feeding in winter when growth slows.
• A fertilizer with added micronutrients supports berry production.

Growth Habit & Display

• Compact, upright shrub with glossy, dark green leaves.
• Produces clusters of bright red berries that persist for months.
• Best displayed in decorative pots indoors or shaded outdoor beds.
• Can be pruned lightly to maintain shape and encourage branching.

Common Issues

• Leaf yellowing: often due to overwatering or poor drainage.
• Berry drop: caused by insufficient light or irregular watering.
• Pests: susceptible to scale insects and mealybugs; treat with neem oil or insecticidal soap.
