How to Grow Osage Orange Seeds (Maclura pomifera)

The Osage Orange (Maclura pomifera), also known as the Hedge Apple or Monkey Ball Tree, is a tough, fast-growing native North American tree prized for its extremely hard, rot-resistant wood, dense thorny growth habit, and large distinctive green fruits. Historically used as living fences and windbreaks across the Great Plains, it is one of the most durable and adaptable trees available. Its bright yellow-green wood is among the hardest in North America and was prized by Native Americans for making bows.

Germination Step-by-Step

Step 1 – Extract Seeds from Fruit

If starting from fresh fruit, break apart the fruit and extract the seeds. Rinse seeds thoroughly and allow to dry briefly before stratification.

Step 2 – Cold Stratify 30-60 Days

Place seeds in a zip-lock bag with moist peat moss or vermiculite and refrigerate for 30-60 days. Cold stratification breaks dormancy and significantly improves germination rates.

Step 3 – Sow 1/2 Inch Deep

After stratification, sow seeds 1/2 inch deep in well-draining soil. Keep soil consistently moist and maintain temperatures of 65-75°F.

Step 4 – Germination in 2-4 Weeks

Expect germination within 2-4 weeks after stratification with warm, moist conditions.
