How to Grow Mounted Anthurium

Mounted Anthurium

Anthurium andraeanum

flower

Mounted Anthuriums are tropical flowering plants grown on wooden plaques, cork, or tree fern fiber rather than in traditional pots, mimicking their natural epiphytic growth habit. They produce distinctive waxy, heart-shaped spathes in red, pink, white, or bi-colors, with protruding golden or cream-colored spadices. This mounting method creates an elegant, naturalistic display that showcases the plant's cascading aerial roots.

Growing Conditions

☀️
Sun: Bright, indirect light; 12,000-15,000 lux recommended; 3-4 hours of morning sun or dappled afternoon light; avoid harsh direct sun which causes leaf burn
💧
Water: Keep moss mount consistently moist but not waterlogged; mist or soak mount 2-3 times weekly depending on humidity and season; in dry climates, daily misting may be needed; reduce frequency in winter; ensure water drains freely
📏
Spacing: Not applicable for mounted specimens; allow 12-18 inches between mounted plants if displaying multiple inches
📅
Days to maturity: 180-365 days to first bloom on newly mounted specimens
🌱
Planting depth: Secure rhizome to mount surface with fishing line or plant ties; aerial roots will naturally attach to mount over 4-8 weeks

Soil

Type: Epiphytic growing medium: sphagnum moss, orchid bark, coconut husk chips, or tree fern fiber
pH: 5.5-6.5
Amendments:
Orchid bark or charcoal for drainage Sphagnum moss for moisture retention Perlite for aeration Worm castings for gentle nutrition

Growth Stages

1

Establishment

4-8 weeks

Freshly mounted plant with visible aerial roots and exposed rhizome; initial adjustment phase as roots seek moisture

Maintain high humidity (60-80%); daily misting essential; secure plant firmly to mount; avoid moving; keep in warm location (70-80°F)

2

Vegetative Growth

2-3 months

Aerial roots proliferate and attach to mount; new leaves emerge regularly; plant becomes more established on substrate

Continue frequent misting; roots should be visible on mount surface; apply diluted liquid fertilizer every 2-3 weeks; maintain consistent warmth and humidity

3

Bud Formation

3-6 weeks

Small greenish protrusions appear at leaf axils; visible pre-flowering structures developing

Maintain excellent light conditions; ensure consistent watering and humidity; do not relocate; provide balanced fertilizer with slightly higher phosphorus

4

Flowering

6-8 weeks per bloom cycle

Spathes unfurl with distinctive waxy texture in red, pink, white, or bi-color; central spadix extends and matures; flowers persist 6-8 weeks

Support heavy blooms if needed; maintain bright light to intensify color; continue regular misting; avoid temperature fluctuations; fertilize every 2 weeks

5

Post-Flowering & Rest

4-8 weeks between cycles

Spathes fade and eventually drop; plant redirects energy to new growth and root development

Remove spent flowers; reduce fertilizer slightly; maintain conditions for next bloom cycle; new blooms typically emerge every 4-8 weeks on established plants

Common Pests

  • Spray with neem oil or insecticidal soap; isolate plant; inspect regularly; wipe leaves with 70% isopropyl alcohol on cotton swab

  • Increase humidity to 60%+ to deter; mist frequently; use miticide if severe; discard heavily infested mounts

  • Hand-pick visible scales; treat with horticultural oil or neem oil every 7-10 days; isolate infected plants

  • Remove damaged flowers; use yellow sticky traps; apply neem oil spray; increase humidity

  • and (Xanthomonas)

    Ensure excellent drainage; avoid waterlogging; remove infected sections; improve air circulation; use sterilized tools; discard severely affected mounts

Uses

🍳

Ornamental Arrangements & Floristry

Culinary

Anthurium flowers are prized as long-lasting cut flowers for floral arrangements, providing weeks of color and exotic appeal. The waxy, sculptural spathes add architectural interest to bouquets and display arrangements. [source]

🏠

Interior Décor & Living Wall Display

Household

Mounted Anthuriums create stunning living wall installations and dramatic focal points in homes and offices. The epiphytic mounting method allows vertical gardening while maintaining the plant's natural aesthetic. [source]

🏠

Air Purification

Household

Anthuriums are documented by NASA studies to filter air pollutants including ammonia, formaldehyde, and xylene, improving indoor air quality. A single plant can help purify a medium-sized room. [source]

💊

Traditional Tropical Medicine

Medicinal

In tropical regions, Anthurium species have been used in folk medicine preparations, though scientific evidence is limited. Modern research focuses on potential antimicrobial and anti-inflammatory compounds. [source]

🦋

Hummingbird & Pollinator Attraction

Wildlife

The bright, waxy spathes and spadix attract hummingbirds and tropical pollinators in their native habitat. In outdoor tropical settings (zones 10-11), mounted Anthuriums can support local pollinator populations. [source]

Harvest Tips

Anthuriums are ornamental cut flowers; harvest spathes when fully unfurled and color is vibrant (typically 3-4 weeks after opening); cut at the base of the peduncle with sharp, sterilized shears; fresh flowers last 2-3 weeks in a vase with fresh water changed every 3-5 days; blooms continue on the mounted plant for extended periods, so regular harvesting encourages more flowers

Fun Facts

  • 🌱 Mounted Anthuriums mimic their natural growth as epiphytes on rainforest trees; in the wild, they climb high into the canopy, with roots dangling freely and absorbing moisture and nutrients from the air, rain, and decomposing plant matter.
  • 🌱 The 'flower' that people admire is actually not a true flower but an inflorescence: the colorful spathe is a modified leaf (bract), while the true flowers are tiny and clustered on the central spadix, which can contain hundreds of individual flowers.
  • 🌱 Anthuriums can bloom almost year-round under optimal conditions, with mature mounted specimens producing flowers every 4-8 weeks, making them one of the longest and most reliably flowering tropical houseplants available.
