By tulip tree I mean this one
Tulip Poplar (Liriodendron tulipifera)
I collected many seeds from the only Tulip tree I know of for miles, it's very old and rare here, this used to be farmland and woods in the 40s and earlier!
Naturally they have a low germination rate so I can't guarantee seedlings but I'll try to send enough to increase the odds, I only collected the healthiest looking seeds.
I've had the seeds outside for 2 months stored in a bag of snow and dirt just like outside in the 20s, because they need cold stratification to sprout. Not sure how long they need it but I NEVER let the seeds dry out completely this seems to kill them in other words store in fridge with some dirt or plant right away.
Send a tree mail with your address if interested.
