For trade or...

The vegetable and squash seeds for trade were all hand pollinated.

Heirloom watermelon. Orange flesh. Dozens of seeds. Seeds were traded to us last summer. Planting three in a hill, two thirds of the seeds we've planted have sprouted.
Snow peas. Dozens of seeds. We planted over sixty of the same seeds this year, all but half a dozen sprouted, grew and produced.

Buttercrisp/crunch lettuce. Hundreds of seeds. We've plantd them. They grew.
Spinach. Hundreds of seeds. All but a few of what we planted this spring sprouted and matured.

Pumpkin seeds. Large variety. 50 plus pounds. Orange in color. Hundreds of seeds. (still waiting for the new plantings to sprout)
Green melon (kinda like a honeydew hybrid.) Dozens of seeds.

Cantaloupe. Hundreds of seeds.

Spaghetti squash. A couple dozen seeds.

Butternut squash. Over a hundred seeds.

Acorn squash. Four or five dozen seeds.

'Mystery" squash: A few dozen.

"Mystery" watermelon. About a dozen. Could be Baby Sweet or an hierloom. Dunno for sure.

FLOWERS:
We have approx three hundred tall bearded irises, mostly violet in color. Willing to trade a few dozen of those for something else.

More ornamental onions than we can count. (resembles a christophi, but grows eighteen inches tall with purple blooms that resemble a sparkler on the fourth of July.)
trading futures:

This summer and/or fall;

Hollyhock seeds, when they go to seed later this summer.

Jumbo garlic and a run of the mill unknown variety. Good, strong flavor from both. (A few dozen of the latter are still on hand, stored above the fridge.)

Next year;

Some lavender plants and/or seeds.

Mebbe...mebbe a few of our early season strawberries.

Two or three years from now;
Gladiolus bulbs and Blazing Star corms.
