This is a longshot, but -- I have a lychee tree that's fruiting right now, with more fruits than I know what to do with, and I'm about to go on a road trip from Florida to the midwest in a week or so. I could drop off a bucket along the way. Shoot me an email at concat("ksymph0", "@", "proton.me") if you're in the area.

Curious:

Where do you live, if I may ask?

Im in centrel europe, and they do ont grow here, though I can get some on a regular base (while it is actually niche fruit here)

Have you tried Rambutan
