How to Propagate Texas Ebony (Pithecellobium flexicaule) from Seed

About Texas Ebony

Texas ebony (Pithecellobium flexicaule), also called Mexican ebony or false acacia, is an evergreen native to Texas and northern Mexico (USDA zones 8–11). A low-maintenance, drought-tolerant tree once established, it produces pale yellow to white flowers from late winter to early spring. Propagation is straightforward from ripe seed.

Step-by-Step Seed Propagation

Step 1: Harvest Ripe Pods

Wait until pods turn brownish-black, dry, and split open easily on the tree. Collect fully dried pods.

Step 2: Extract and Scarify Seeds

Open pods and remove seeds. Nick each seed coat with a knife, then soak in water for 24 hours to improve germination.

Step 3: Prepare Growing Medium

Use a well-draining organic potting mix in containers, or sow directly in garden soil at the same depth.

Step 4: Sow Seeds

Make a 1-inch hole in the center of each container. Place one seed per hole, cover with soil, and water thoroughly until it drains from the bottom.

Step 5: Provide Warmth and Light

Place containers in full sun. Texas ebony germinates best in warm, bright conditions.

Step 6: Maintain Moisture Until Established

Keep soil consistently moist (not soggy) until germination, which may take up to two months. After sprouting, water 2–3 times weekly until the seedling establishes. Mature trees are highly drought-tolerant.

Step 7: Transplant

After ~6 months, when the root system is robust, transplant to the garden. Space trees 20–30 feet apart.

With patience during the slow germination phase, Texas ebony rewards growers with a handsome, resilient evergreen.
