Mimosa Tree Seeds

(Albizia julibrissin)

Albizia julibrissin, commonly known as the Persian silk tree or Mimosa tree, is a fast-growing, deciduous tree native to southwestern and eastern Asia. It is popular for its feathery, fern-like foliage and stunning, silky pink flowers. 

Botanical Overview:

• Family: Fabaceae (legume family)
• Height: Typically grows 20-40 feet (6-12 meters) tall.
• Crown Shape: Broad, umbrella-like canopy with a flattened crown, providing light shade.
• Leaves: Bipinnately compound, fern-like leaves, about 10-20 inches long. They are sensitive, folding during the night or when touched.
• Flowers: Showy, pink, or white fluffy flower clusters, blooming from late spring to mid-summer. The flowers are highly fragrant and attract bees, butterflies, and hummingbirds.
• Fruit: Flat, brown seed pods, about 5-7 inches long, containing multiple seeds. These pods persist through winter.

Growth Conditions:

• Soil: Tolerates a wide range of soil types, including poor, sandy, or clay soils. Prefers well-drained soils.
• Light: Thrives in full sun but can tolerate light shade.
• Watering: Drought-tolerant once established, though it benefits from occasional watering during dry periods.
• Hardiness Zones: USDA zones 6-9, but it can be invasive in some regions due to its rapid spread by seed.

Uses:

• Ornamental: Widely planted as an ornamental tree in gardens and parks for its beauty and light shade.
• Medicinal: In traditional Chinese medicine, the bark and flowers are used to treat conditions such as anxiety and depression.

Zones: 6 to 9

Stratification Requirement: Scarify the seed and sow.

Planting Instructions:

Planting Mimosa tree seeds involves a few key steps to ensure successful germination and growth. Here's a simple guide:

Seed Preparation

• Scarification: Silk tree seeds have a tough outer shell, so you need to help them absorb water. Gently rub the seeds with sandpaper or nick them with a knife.
• Soaking: After scarifying, soak the seeds in warm water for 24 hours. This softens the seed coat and promotes germination.

Soil and Location

• Choose well-draining soil with good fertility. Mimosa trees can adapt to various soil types but prefers sandy or loamy soils.
• Select a sunny location, as the tree thrives in full sunlight.

Planting the Seeds

• Sow the seeds about half an inch deep in the soil.
• Cover lightly with soil and press it down gently to ensure good seed-to-soil contact.

Watering

• Water the soil thoroughly after planting, but avoid overwatering.
• Keep the soil moist but not soggy during the germination period.

Temperature and Care

• Mimosa tree seeds germinate best in warm temperatures. Keep them in a location that stays warm, whether outdoors or in a greenhouse.
• Once the seedlings emerge, ensure they get plenty of sunlight and continue to water them regularly, allowing the soil to dry slightly between waterings.

Transplanting

• Once the seedlings are a few inches tall and have developed a strong root system, they can be transplanted to their permanent location.

The silk tree is a hardy, fast-growing plant that can thrive in various conditions, but the initial care during the germination phase is crucial for success.
