Albizia julibrissin 'Rosea'

Pink Silk Tree / Mimosa Tree

A deciduous ornamental tree with spectacular pink, pom-pom-like flower clusters

About Albizia julibrissin 'Rosea'

Albizia julibrissin 'Rosea', commonly known as the Pink Silk Tree or Mimosa Tree, is a deciduous ornamental species native to southwestern and eastern Asia. This cultivar features a distinctive broad, umbrella-shaped canopy with delicate, feathery compound leaves that demonstrate nyctinastic movement, folding in the evening or when touched.

The tree is primarily valued for its spectacular summer display of silky, pink, pom-pom-like flower clusters that emerge from June through August. Reaching heights of 6-12 meters (20-40 feet) at maturity with a similar spread, Albizia julibrissin 'Rosea' provides an elegant, tropical appearance in temperate landscapes. The tree produces flat, bean-like seed pods that mature to a light brown color in autumn.

🌸 Distinctive Features: The Pink Silk Tree's dramatic pendulous flowers and feathery foliage create a remarkable visual display. Its ability to provide dappled shade and create valuable habitat for pollinators makes it an excellent choice for landscape applications requiring both ornamental beauty and ecological benefits.

This species offers exceptional ornamental qualities with its fast growth rate, striking summer flowers, and attractive foliage that creates a tropical aesthetic in temperate environments. Once established, the Pink Silk Tree is remarkably drought tolerant and requires minimal maintenance, making it an ideal specimen for discerning gardeners and landscape professionals.

Germination Time
2-4 weeks
Optimal Temperature
20-25°C
Success Rate
High w/ Scarification

Key Information

  • Germination Rating: 3.5/5.0 (moderate difficulty due to seed coat dormancy)
  • Germination Time: 2-4 weeks after scarification
  • Optimal Temperature: 20-25°C (68-77°F)
  • Viability: Seeds maintain good viability for 2-3 years when properly stored
  • Germination Medium: Well-draining, fertile soil mix
  • Success Rate: High with proper scarification; low without pre-treatment
🔑 Critical: Seed Coat Dormancy: Seeds of Albizia julibrissin 'Rosea' feature a hard seed coat that requires specific pre-treatment to achieve successful germination. With proper scarification techniques and optimal growing conditions, these seeds offer a cost-effective method of propagation.

Planting Instructions

Seed Selection & Scarification

  • Collect or purchase mature seeds from established pods, selecting those that appear full and undamaged
  • Scarify seeds by one of these methods:
    • Nick the seed coat with a small file or sandpaper
    • Soak in concentrated sulfuric acid for 20-30 minutes (professional method)
    • Pour boiling water over seeds and allow them to soak for 24 hours as water cools

Planting Medium & Depth

After scarification, plant seeds at a depth of approximately 1 cm (0.4 inches) in a well-draining growing medium. Use a fertile soil mix to support early seedling development and establishment.

Temperature & Moisture

Maintain soil moisture at consistently damp but not saturated levels. Provide bottom heat of 20-25°C (68-77°F) if possible to enhance germination rates. Germination typically occurs within 2-4 weeks when properly scarified.

Monitoring & Care

Monitor regularly and maintain adequate ventilation to prevent fungal issues. Once seeds germinate and develop primary leaves, gradually reduce humidity and increase light exposure to support healthy seedling growth.

Light Requirements

Optimal Conditions: Full sun to partial shade with minimum 6 hours direct sunlight daily. Maximum sun exposure promotes flowering and optimal growth rates, while some afternoon shade can be beneficial in extremely hot climates.

Watering Needs

Regular watering during establishment phase is essential for developing strong root systems. Once established, the Pink Silk Tree demonstrates excellent drought tolerance and requires minimal supplemental watering except in prolonged dry periods.

Soil Preferences

Adapts to various soil types but prefers well-draining, slightly acidic to neutral soils. The tree is tolerant of poor soils and demonstrates remarkable adaptability once established. Avoid waterlogged or clay-heavy soils that impede drainage.

Fertilization Program

Apply balanced, slow-release fertilizer in spring after the first year of establishment. Use a formulation with moderate nitrogen levels to support vegetative and floral development without promoting excessive growth.

Transplanting

Transplant to individual containers when seedlings reach 10-15 cm in height. Time final landscape planting after risk of frost has passed. Handle carefully to minimize root disturbance during transplanting operations.

Protection & Hardiness

Provide wind protection for young specimens to support establishment. May require winter protection in colder zones. The Pink Silk Tree's deciduous habit provides natural winter dormancy adaptation to temperate climates.
