Growing and Maintenance Tips:


Maclura tolerates urban pollution, drought, moisture, heat and a variety of soil conditions, including a variable pH. Can be grown as low or high stemmed tree form. Maclura branches are sharp with thorns, making it a good hedging plant or barrier. Older branches lose their thorns.

Additional Notes about Osage Orange:


While the inedible fruits somewhat resemble oranges in texture, they are not related to oranges.  A member of the fig family, each fruit is actually a dense cluster of hundreds of small fruits.

A bright yellow dye can be extracted from the wood, which is also very rot-resistant. 

The wood from Maclura is among the hardest in the world, and produces the greatest heat-energy per cubic inch of all the trees native to Ontario. While not officially native to Ontario, it's pretty close.
