I casually partook in this thread last year, and casually had a garden, but baby arrived mid-August so the garden was mostly weeds and my internet participation nose-dived. This year will be better!
Harvested: rhubarb from a friend. Made it into a rhubarb crumble and a rhubarb syrup to doctor up gin and tonics. Both so good.
So far, on the 'impossible to kill' front I've got chives, chinese onion, walking onion, lemon balm and mint galore, with new additions of horseradish, strawberries and a raspberry cane that migrated over from the neighbour.
In the ground and thriving: spinach, pac choi, swiss chard, kale, radishes.
In the ground and never to appear: carrots (confirmed), lettuces (confirmed), beets (TBD). I've never done the seed germination test, and as I attempt to use the same seeds for a few years... I should probably start.
In the ground and struggling: a gifted tomato seedling (too early?), and calendula, basil and onion seedlings that I started without a proper light set up... they struggled on the window sill and continue to struggle in the ground. We'll see.
Getting rotated in and out of my house all day: zucchini! I'm determined to have fruitful zucchini this year.
Still to plant: beans (from seed), cucumbers, tomatoes and maybe peppers (seedlings.)
