Swedes and turnips. Swedes don't even bother to germinate and turnips germinate, then struggle and eventually die. Think I pulled about 3 last year, and they were all riddled with holes!! Carrots can be patchy but am sowing so many rows this year I HAVE to get some! Basil germinates, then either grows like the clappers, or all dies.
Terrance, angelica I can grow! I grew some from seed last spring and it looked wonderful in my garden. I let it flower and set seed, which is distributed exactly where I wanted it to, and already it is a foot high and lush!
