Growing Mimosa (Albizia julibrissin) from Seed: Pod to Seedling

Propagating Silk Tree from Seed

Mimosa seeds are inside flat, brown pods that resemble locust pods (it’s a legume).

Seed Preparation

1. Collect brown, dry pods; remove the flat, hard, brown seeds.
2. No stratification needed; they germinate like beans.

Sowing

1. Plant ½ inch deep in pots at 75°F (24°C).
2. Keep moist; germination in 10–20 days.
3. First leaves are simple; second leaves are ferny (true leaves).
4. Prick out at 2–3 inches tall into individual pots.
5. Harden off 10 days in shade after last frost; plant in full sun.

Caution

Mimosa is invasive in many areas (especially Southeast U.S.). Check local regulations before planting.
