Has anyone rooted Hedge Apples

[just_sawing]

I am taking a Plant Propagation class at College and my Paper over the semester is going to be propagating Hedge apples.
I will be doing the seeds, Rooting and clippings. Has anyone done this with the Hedge Apple?

Most likely, you want to clean the seeds of any pulp, as there are frequently germination inhibitors present in fleshy fruits. Next you will want to store the seeds in moist, not soggy, sand for a couple of months in your refrigerator or outside for the winter. Plant the seeds when it gets warm in the spring.

Those are my best guesses, now I'll go look it up. ;D

One old thread about it. I swear I also asked about once a pony time and seem to remember being told to mash the apple to a pulp and use that to start the seeds.
