These aren't listed in your wants but I have Mulberry Tree seeds and Quince Tree seeds. Both are fruits. If you are interested I would like to trade for your Schisandra chinensis and Ginkgo biloba. Thanks.

My orchard is on a rocky hillside and seems happy growing there. The same trees are growing down in the valley on level ground. The difference is the amount of work I must do. Picking from a ladder on a hillside is not easy. Therefor I try to keep my trees short. Using my tractor on a hillside is dangerous, and the roll bars to protect me in case of a rollover will not fit under a short tree. I am forced to cultivate with a roto tiller, not easy on a hillside. My soil is clay/loam and takes rain without runoff and is not subject to slides. I hope this gives you something to think about.

Here's a link to that thread if anyone's interested: Here is a link that might be useful: Ginkgo nuts/fruits/rash Thread in the Conifers Forum

The nut looks like a black Walnut... I thought the fruit looked like passion fruit... but I always thought the seeds had color around them.
