Paulownia Tomentosa – Premium Bare Root Cuttings (Pure Species)

Paulownia tomentosa, also known as the Princess Tree or Empress Tree, is one of the most iconic and widely cultivated Paulownia species in the world. Native to China, this pure species is admired for its exceptionally fast growth, huge heart-shaped leaves, and spectacular lavender-white blossoms that fill the spring air with a light vanilla fragrance.

Unlike hybrids that are designed for maximum timber output, tomentosa is prized for its ornamental beauty, ecological value, and versatility. It is commonly planted in gardens, parks, boulevards, agroforestry systems, and reforestation projects, thanks to its adaptability to a wide range of soils and climates.

Each root cutting offered by GreenSeed Paulownia is premium Grade A, hand-selected for health and size. These roots are prepared for spring planting, ensuring rapid establishment and vigorous growth from the first year.

⭐ Key Characteristics

Pure species (non-hybrid): valued for ornamental beauty, ecological benefits, and traditional uses.
Very fast growth: reaches 3–4 meters per year in favourable conditions.
Cold-resistant: tolerates winter temperatures down to –20 / –25 °C, suitable for temperate regions.
Striking spring blossoms: displays large clusters of lavender-purple flowers with subtle yellow streaks, known for their pleasant fragrance.
Decorative foliage: produces huge, heart-shaped leaves (up to 30 cm), ideal for shade and ornamental planting.
High timber potential: yields lightweight, stable wood widely used for furniture, veneer, musical instruments, crafts, and carving.
Ecological benefits: improves soil quality, promotes biodiversity, resists drought once established, and contributes significantly to CO₂ absorption.
Highly versatile: suitable for urban landscaping, ecological restoration, ornamental projects, and multipurpose plantations.

Required Materials

Fine, sterile seed-starting mix (peat/coco + perlite), light and well-draining
Seed trays, small pots, or a mini-greenhouse
Fine mist sprayer or watering can with a soft rose
Clear lid, plastic film, or humidity dome
Thermometer or heat mat to maintain 20–25 °C (68–77 °F)
Bright growing area or horticultural LED light (PPFD 100–250 μmol/m²/s)

1) Stratification (Cold Treatment)

Optional but recommended to achieve uniform germination.

Mix the seeds with a slightly moist substrate (fine sand, vermiculite, or light seed mix).
Place the mixture in an airtight bag or sealed container.
Refrigerate at about 4 °C (39 °F) for 4–12 weeks.

2) Sowing

Fill containers with pre-moistened substrate (moist but not waterlogged).
Scatter the seeds on the surface — do not cover; they need light to germinate.
Mist gently with water.
Cover with a clear lid or humidity dome.
For large-scale production, use a misting chamber or heated propagation bench.

3) Germination Conditions

Temperature: 20–25 °C (68–77 °F), stable
Light: bright indirect light or LED grow lighting
Duration: usually 10–20 days
Substrate: always slightly moist, never waterlogged
Ventilation: avoid cold drafts but ensure minimal air exchange

4) After Germination (Critical Phase)

Open the lid slightly each day to reduce excess humidity.
Gradually increase ventilation to strengthen stems.
Remove the cover completely once seedlings have 1–2 true leaves.
Maintain strong light to prevent weak, elongated seedlings.

5) Transplanting & Early Growth

Transplant when seedlings reach 10–15 cm (4–6 in) or show 2–3 true leaves.
Use individual pots (7–10 cm) for optimal root development.
Keep plants in bright shade for 3–5 days after transplanting, then gradually expose them to full sun over 1–2 weeks.
Water moderately: avoid both drought and excess moisture.
Optional for production: apply a light, balanced fertilizer after 3–4 weeks (e.g. NPK 10-10-10).

PHASE 1 — POT CULTURE (UNDER COVER)

Objective: ensure maximum rooting success, protect plants from frost, and achieve uniform sprouting.

1) Rehydration (mandatory)

Before planting:

Soak the root cuttings in clean water for 5 minutes.
→ This reactivates the tissues and improves the success rate.

⚠️ Do not exceed 5 minutes.

2) Start Period

Early spring
Ideal temperature: 15–25 °C (59–77 °F)
Under a greenhouse, tunnel, or bright sheltered area

3) Pot Planting

Use individual pots for optimal root development and uniform emergence.

✔️ Root orientation

Place the thicker end upward (bud side).
Insert the root slightly angled (20–30°)
→ Promotes activation of the upper buds.

✔️ Covering

Cover the root with no more than 1 cm of substrate.
(Buds must remain close to the surface.)

4) Recommended Substrate

A heavy substrate slows down emergence. A light, airy mix ensures faster and stronger sprouting.

Use:

Fine horticultural potting mix
Light, well-draining substrate
Optional: perlite for extra aeration

‼️ Paulownia does not tolerate excess water.

5) Watering (pot phase)

Water moderately after planting.
Keep the substrate slightly and consistently moist.
Never waterlog the pot.
Avoid all standing water.

6) Sprout Emergence

Timing depends on temperature and conditions:

Sprouting usually occurs 3 to 8 weeks after planting.
Faster in warm and stable environments.

In case of cold weather or late frost:
→ Cover pots with frost protection fleece.
