I know what you did last summer

Nasturtium.
I've mentioned before that we grew some edible flowers, Sakata Sweet melons, and Tigger melons last year.
Here are a few of the other things we tried for the first time.

Plum Granny.
Supposed to be an heirloom "pocket" melon. (Somewhere between the size of a golf ball and a clementine.) I read that they were grown primarily for scent. They're so bland as to be inedible. They did smell great, but weren't as strong as I'd hoped. Nothing approaching the scent level of daffodils, say. It may vary with growing conditions but I doubt I'll try them again. Some little critters definitely like to eat them -- I think it was the most munched-on thing in the garden.

Japanese eggplant.
We liked these much better than traditional eggplants. They seemed less likely to grow bitter, and were more versatile for cooking just because of their size. We'll definitely grow these again.

Triamble squash.
A winter squash. I ordered these seeds purely based on the look of the pictures, which were idealized to say the least. Still, it's an interesting looking vegetable. But hard, hard, hard to cut. It tastes good, and keeps forever, but I really should have realized that ten-pound squashes were a little much for two people.

These were really picked too soon. (The stem should be dry first.)
I couldn't find a picture, but we also grew lemon cucumbers. I was under the impression that they had a lemony taste, but the name just refers to the size (and color, somewhat). They tasted good enough, but did get bitter sometimes. Plus they have tiny hairs or spines that were difficult to rub off. And they didn't keep well at all -- one day, tops. So, back to white cucumbers for me.
If last year was the year of melon experimentation, this will be the year of the squash! More on that later.
