Hmmm, I don't have much as of yet.
But I will have a long thin cucumber variety and a melon (korean, I believe) that an asian co-worker gave me this spring.
I hesitate to call them heirloom because I have no varietal name to attach to them, but at least the cukes have grown true as best I can tell, and I am still awaiting the first of the melons (small, but very sweet I am told).
If your interested, or if you come across heirloom varieties you are willing to share/trade let me know.
I am slowly trying to convert to as many heirlooms as I can.
Unfortunately I'm limited to tomatoes at the moment.

I'll send you some onion sets for some of your thin cucumber and korean melon seeds.
I've always ordered all my veggie seeds but now I'm trying to go all heirloom too. Well, maybe not all heirloom but at least open pollinated so I can save seeds. So far I've mostly just got tomatoes too. You wouldn't have any Porter tomato seeds would you HotPepperDad?

No, I only have Cherokee purple and Brandywine.

I haven't harvested any seeds yet, but I can attest to the flavor of the "thin" cukes. Much better than the Burpee straight 8 I planted along with them.
Also, the straight 8 cukes do not seem to tolerate the heat, they quickly blanch and become bitter.
The cukes I got from my friend have held up very nicely in the hot weather, staying firm and green.

Anyway, I'll harvest some cuke seeds this weekend.
Do you want to try and plant them this year, or wait till next?
I planted these in late May/early June I think, and they started producing over the past week or two, so I think you could easily grow them for this year with the long season here.

Also, if your intersted in Canteloupes, I have been pleasantly suprised by the results I got from a burpee variety called Sweet N' Early. They were planted in early May and I harvested the 1st 3 this week. The package states they come from Peru, so I assume they are open polinated, but I need to do some more research.
